Don't share WorldMapCollection. Fixes BUKKIT-4871

WorldMapCollection stores scoreboard, map (item), structure, and
village information. Scoreboards are explicitly handled globally,
while villages and structures are erroneously shared.

This commit separates the WorldMapCollections to not be shared among
custom worlds. Maps are special-cased to maintain the previous shared
behavior.
Ensure maps are stored only in the main world. Fixes BUKKIT-4872
Updated version to 1.6.4-R2.0 in pom.xml for RB.
Updated version to 1.6.4-R2.1-SNAPSHOT for development towards next release.
Update CraftBukkit to Minecraft 1.7.2
Forward exceptions to log4j, cleanup logger handling. Fixes BUKKIT-4948
Handle JUL logger formatting
Make console work on Windows again. Fixes BUKKIT-4956

Something the log4j ConsoleAppender does makes the console work correctly
on Windows. After trying to pull pieces of it out and run them manually
I decided to just put the appender back. We now once again start with the
ConsoleAppender then remove it immediately after starting.
Correctly send player names for the tab list. Fixes BUKKIT-4925
Handle ChatColor-ending messages FIXES BUKKIT-4924

Now adds the component upon creation, eliminating issues where the
created component was discarded.
Fix fishing ignoring event experience.
Fix missed doors diff. Fixes BUKKIT-4908

l previously was the block id, however Minecraft's refactoring means that
the method is now passed a Block reference rather than the id.  l is now
the data value of the block, so the block retrieved with that value is not
the correct block to be testing.
Add ConsoleAppender from log4j for diff visibility
Catch all exceptions in jansi initialization. Fixes BUKKIT-4936

Both log4j and our own jline/jansi initialization attempt to catch
errors caused by jansi's use of native libraries. However both of them use
the Exception type which does not catch all errors. On Windows Server 2008
R2 Enterprise without installing extra software the required C++ libraries
are not available which causes an error that does not extend Exception. To
ensure we catch all errors I've changed both of these to catch Throwable
instead which gets us a working console minus jansi functionality.
Correctly drop BlockBreakEvent experience. Fixes BUKKIT-4942

This was a missed diff from the update.
Use correct packet data for toggling flying. Fixes BUKKIT-4989
Use strict lookup for op permission refresh. Fixes BUKKIT-4698

Adding or removing operators was mistakenly using a loose player lookup
method, which would cause a permission refreshes on an online player whos
name starts with the name of the (offline) opped player.

Add/Remove op operations are exact name match only and the permission
refresh will behave the same way.
Added RecipeBookClone from nms for diff visibility
Fix written books crashing the server. Fixes BUKKIT-4945

CraftBukkit modifies the IRecipe interface, adding new methods, so all
classes that implement IRecipe need to be imported and modified to add the
new methods.

Extending ShapelessRecipes implements the added methods and allows
RecipeBookClone to work with the Recipes API in a way that is consistent
with similar recipes, even if the recipe information present in the API
isn't technically correct.
Fix BlockCanBuildEvent returning null. Fixes BUKKIT-4972

A Block object is now passed in place of the previous id value, so the
obfuscated name for all subsequent arguments was shifted.  As such,
BlockCanBuildEvent was using the incorrect values for both the material
and the location of the event.

This is corrected by swapping the values into the correct order and
providing an id based upon the Block passed into the method.
