Updated colors of tile items 1-30 to match map colors.

Fixed a few unknowns and typos in tile items 1-30 as well.
Updated colors of tile items 30-40 to match map colors.

Left 38 Gray Brick #FF909090 rather than changing it to match the #FF808080 of the map as 1 Stone Block is also #FF808080.
Updated colors of tile items 41-62 to match map colors.

Renamed 42 Lantern/"Bulb" to "Star in a Bottle".
Renamed 51 Cobweb to Web to match map behavior. 
Changed 54 Glass alpha channel to FF to match map behavior (along with matching the map color as well).
Updated colors of tile items 63-79 to match map colors.
Updated colors of tile items 80-100 to match map colors.

Left 82, 83, 84 Herbs as-is since each herb type (Daybloom, Moonglow, etc...) has its own color on the map. 21 Chests, 26 Altars, and 31 Orbs also have this issue of sub-items having different colors. I'll see about opening an issue into this.
Updated colors of tile items 101-120 to match map colors.

105 Statues has the aforementioned issue of sub-items having different colors, namely the vases being a different color than the statues.
Increased color luminance of tile item 30 Wood.

By 12.5% to differentiate from 0 Dirt Block and 5 Tree. The same as the difference between 1 Stone Block and 38 Gray Brick.
Updated colors of tile items 121-131 to match map colors.

130 Active Stone Block is #FF808080 on the map to prevent obvious detection of traps. For the editor it obviously needs to be easily discernible, so I kept it brighter than both 1 Stone and 38 Gray Brick, but slightly reduced it from #FFA5A5A5 to #FFA0A0A0 to keep the luminance a multiple of 16. OCD is a terrible thing. ;)
Updated colors of tile items 132-139 to match map colors.

133 Forge, 134 Anvil Hardmode, and 137 Trap all have the aforementioned issue of sub-items having different colors.

135 Pressure Plate has no color on the map and was left as-is.

138 Boulder reduced from #FF636363 to #FF606060, same reasoning as 130 Active Stone Block. ;)
Updated colors of tile items 140-149 to match map colors.

As 147 Snow Block and 148 Snow Brick are identically colored on the map, I applied the same HSL reduction percentages to 148 Snow Brick as between 161 Ice Block and 206 Ice Brick.

149 Christmas Light is bizarre, those that anchor bottom are green on the map, those that anchor left or right are blue, and those that anchor top are reddish. Regardless of actual light color or on/off status. I went with the anchor top reddish color to maintain consistency with the prior pure red color.
Updated colors of tile items 150-169 to match map colors. Added Blends="true" as needed.

Renamed 165 Large Deco to Icicle.
Updated colors of tile items 170-177 to match map colors. More...

Add UV coords and placement for the lights. Added Blends="true" where needed.
Reverted 165 Large Deco name from Icicle change. Updated color also.

I determined that 165 Large Deco is also used as the stalactites/stalagmites in the caves, so I reverted the name change and changed the color to the cave grey color instead of the ice blue color since that works better for both situations.

It also has a number of frames, I'll delve into that in a later commit.
Updated colors of tile items 178-185 to match map colors. More...

178 Gems has the aforementioned issue of sub-items having different colors. For now it is left the default.

179 - 183 have been provisionally named Moss <color> and have been set to Stone="true" and Special="Grass" to properly blend.

184 has been named Moss Plants and needs UV coords mapped out in the future. As well, the different UV coords have different map colors on their respectively colored mosses. For now I've given it the same gray as 165 Deco Large so as to "match" all the moss colors.

185 Deco Small has a plethora of colors for the various sub-items, I went with the bone related color and increased the brightness 12.5% to differentiate it better from 1 Stone.
Restored Framed="true" to 174 Platinum Candle

Copy/paste gone wild. ;)
Updated colors of tile items 186-206 to match map colors. More...

Not touching 186 and 187 at this point. Presumably these are the large "piles" mentioned in the 1.2 patch notes. I've located examples of both, 187 appears in Spider Caves as well as Underworld Ash, while 186 is all over the place.

Other than that, added Blends="true" where needed.

More commits to come tomorrow. :D
Updated colors of tile items 206-220 to match map colors. More...

Incorporated HerbertV's 207 Water Fountain commits for the working fountains.

Added UV coords for 209 Cannon/Bunny Cannon, 212 Snowball Launcher, 216 Rocket colors.

Incorporated HerbertV's frame size fix for 220 Solidifier.
Updated colors of tile items 221-250 to match map colors. More...

Includes #450 227 Dye Plant pull request.
Size changes on a number of framed items.
233 given the default pink color, as well as the proper size. It appears to be bushes of some sort. More investigation needed.
238 Pink Bulb renamed to Plantera's Bulb and given the correct size.
239 Gold Bar renamed to Metal Bar and all UV coords added.
240 renamed to Wall Deco 3x3 and all items named. Should supersede HerbertV's commit.
241,242,245, 246 similarly named Wall Deco XxY and given proper names and UV coords.
248, 249, and 250 given best guess colors as they do not appear on the game's map.
Corrected 175 Tin Brick color.

Another case of copy/paste gone wild.
Updated colors of wall IDs 1-111 to match map colors. More...

Also added plausible names for a number of unnamed walls, mainly the cave walls and the jungle walls (though those warrant further looking into).

Matched the Dungeon wall names (Brick/Tiled/Slab) with the names listed on the wiki.

A number of walls did not have a color on the map, so a reasonable color was chosen.

Quite a few of the walls (and a few of the bricks) probably could stand some tweaking to make them more discernible on the map.
