Experimental algorithm to floor against AABBs
Move AABB intersection code to Ray class.
Some refactoring before moving on.
Minor stuff.
Merge branch 'master' of github.com:orbweaver/DarkRadiant
Preliminary floor algorithm implemented for brush nodes.
Move algorithm to Brush class, cleanup code.
Fix a few compiler warnings, remove unneeded namespace qualifier.
Preliminary algorithm for Ray-Patch intersection
Move low-level algorithm to Ray class. Refactoring.
Implement ITraceable for MD5 models.
Implement ITraceable for PicoModelNodes.
Better trace start point selection for entities.
Add "Floor Selection" icon and toolbar command
