Added tweak/hack to remove display corruption with Ati cards, commit revision 5937

Corresponding setting: AtiHacks = 1 (default = 0)

Affects CUnitDrawer::DrawUnitBeingBuilt

- when AtiHacks is set to 1, we disable the additional clip-planes, for the duration of drawing the unit with glPolygonMode( GL_LINE )

koshi has updated the settings to have an "AtiHacks" value, appropriately described.
