Only draw thing paths when in things mode
Optimised MapSector::getColour, should be a noticable improvement for large ZDoom+UDMF maps such as ZDCMP2
Changes to the thing path stuff:
- Don't calculate paths every time renderPathedThings is called
- Dragon path stuff disabled for now
(paths should probably be calculated elsewhere - maybe in MapEditor, and only updated/recalculated when needed, as calculating them every frame is very slow, especially noticable in ZDCMP2)
