It would be nice to have the ability to define "selection groups" of brushes &
Entities. This would allow you to select certain things, say, a building and
everything it contains, then define it as a selection group. Then, you could
recall that selection group and it would select those brushes/entities. 

This is different from func_group, this would be independent of the .map file,
could contain entities, brushes, doors, script_movers, spawn points, etc.
