Cleaned and fixed D2k infantry rules a little

Moved Selectable Bounds to infantry default, fixed vertical offset.
Removed some TakeCover duplication.
Added engineer and medic/thumper prone sequences.
Made sure that TakeCover/WithInfantryBody sequence modifiers are applied
properly.

Fixed d2k grenadier sequences offset to match other infantry.
