[PATCH] qbsp: Tweak epsilons 

The choice of the various epsilon values is critical to having geometrically
complex maps compile correctly.

The one which seems most important (so far) is the ANGLE_EPSILON. This one
needs to be quite tight to avoid "bad things" happening when you create small
angles between adjacent surfaces.

Another epsilon inter-relationship I discovered, is that it seems
CONTINUOUS_EPSILON needs to be larger than EQUAL_EPSILON. It seems to play
havoc with the t-junction code otherwise.
