Added a method to easily get named addons from other addons.
Fixed bugs with addonclassloader.
Added ignores to some unavoidable line items
Added auto-cancel to panels so that items cannot be taken from them by
default.
Cleared up the description settings methods. Using these will add to the
description of the item.
Temporarily removed JavaDoc and Source jar creation from the POM to save
time when compiling. Will put it back when we need it.
Also, I worked out how to run the Bukkit server setup for tests. See the
setUp method in the tests. This works (at last).
