Fixed an error that can occur with Furnace recipes.
Replaced Bukkit.getLogger() calls with CraftBookPlugin.logger()

This should make all messages in the console start with [CraftBook]
Fix ContentSensor being pedantic about the amount.
Added CraftBook 3.6.3r2 changelog
CraftBook 3.6.3r3 Changelog
Added footprints mech.
Removed useless code from footprints.
Heavily improve Footprints.
Fixed combine harvester offset.
Made Melody IC require restricted perms to broadcast globally.
Enhanced IC sign caching methods. Should cause less hiccups.
Made chunk anchor force load the chunks in case they are unloaded for
some odd reason. (I don't trust bukkit to keep them loaded)
Greatly enhance the way item parsing is done. Adds support for names,
lores, enchants. Also made CustomCrafting use this item parsing method
to limit code duplication.
Added Variables to CraftBook.

/cb var

Used similar to Batch variables. So %NAME% on a sign. And it'll be
intelligently replaced at runtime with the variable.
Reset IC cache when a variable is changed.
Added boolean and numerical commands to /cb var

They can toggle boolean values and manipulate numbers.
Added per-variable manupulation permissions. Made it just the one
craftbook.variables.modify perm, or craftbook.variables.modify.name

Note: Creation/Getting/Erasing still need their own perm node.
Disallow division by 0 in var commands.
Fixed pipe error with null items.
Fix CustomCrafting extra-results in some circumstances.
