qbsp: treat func_detail entities as additional brushes for worldspawn 

The first step towards supporting detail brushes for Quake 1. This gives
us a way to add detail brushes to a map within the existing mapping tools. A
mapper can simply add a definition for a "func_detail" entity to their
editor and create func_detail entities.

Of course, currently they will behave exactly like world brushes. Future
patches will start to treat them differently.
