updated explosions -- now uses cnc mod's names
updated aircraft rules, as per nyerguds' rules.ini
made crates close to original C&C values + misc.

Nuke powerproxy currently doesnt work so I set its shares to zero.
"allowmultiple" for support powers is broken, and should be fixed.
OpenRA doesn't yet have support for crates full of infantry. 
minor fixes

Silo moved to build queue. Last I checked, GivesBuildableArea didn't work with stuff produced from the support queue.
For whatever reason, you can build FIX in C&C Gold right away. 
misc fixes; bluetiberium

apc is actually AttackFrontal
fixed palette order a bit
harvester harvests BlueTiberium instead of Blue Tiberium.
infantry detect cloaked; grenadierexplode fixed
pre-requisites fix
stealth tank cloak & crushes infantry

Until cloak issues is fixed (https://github.com/OpenRA/OpenRA/issues/2898), 90 seems a reasonable cloak delay.
Stealth tank now crushes infantry.
Cloak sound fixed.
