Subject: [PATCH] Per entity (type) collision settings
Base patch was the only player collisions patch, the original author of was tr7zw <tr7zw@live.de>
but pretty much the whole implementation changed.
This patch implements per entity (type) collision settings with 100% compatibility with bukkit api and
vanilla.
The whole code is based around 1 class, the EntityFilter class. Whole filtering logic is there.
