Fix attributes not clearing on death. Fixes BUKKIT-5213

Due to an incorrect mapping of this method to a friendly name, we're
unfortunately calling the wrong method within EntityPlayer.reset() to
reset attributes. Instead of what we've mapped as "removeAllEffects", we
should be calling EntityLiving.aP(). This mapping should be corrected in
the next naming version.
Account for different reach limit in Survival/Creative. Fixes BUKKIT-4257

When we first added the reach limiter in CraftBukkit there was no
difference between how far the client could reach in vanilla while in
Survival or Creative. At some point in Minecraft's cycle Creative was
given a block extra to work with and our protection was not updated to
account for this. We need to respect the possibility of different game
modes in Minecraft providing the client with varying reach distances.
[Bleeding] Send short version string on ping. Addresses BUKKIT-5206

With the update in 1.7 that improved the server ping, it was made to
include a long version string for CraftBukkit. This value is too long
for proper display so we now send a shortened string consisting of
the server implementation and the minecraft version.
[Bleeding] Call event when reflecting fireballs. Adds BUKKIT-5214
[Bleeding] Fix crash involving horse passengers. Fixes BUKKIT-5212

Setting a horse's passenger to a non-living entity will cause a
server crash when the horse ticks, we need to check that it is
a living entity before casting, and skip otherwise.
[Bleeding] Handle custom furnace recipes separately. Fixes BUKKIT-1657, BUKKIT-3846

Due to vanilla blanket comparing data values, and the unspecified
order of hashmap iterators, we need to run through custom recipes
first, and therefore separately, to ensure that they are actually
used. By not adding the custom results to the experience table, we do
not override the experience gains from vanilla smelting recipes.
