Moved Selectable Bounds to infantry default and tweaked them to better
match art size.
Gave Viceroids their own default. They don't share cells anymore, either.
Fixed JumJet voice.
Disabled RevealsShroud on Tiberian Fiend.
Cleaned up TakeCover definitions.
Tweaked selection bounds of TS cyborgs.
Changed TS engineer trait order to fix prone animations not showing up.
The order is not the same as the original one (influenced by dependencies) but the main point is to have standard infantry (E1) first, E2 second, ENGINEER third, and the special units on last places. The biggest difference to the original is GDI MEDIC as last (which also applies when both GDI and NOD units are available).
