infantry anims: running ticks corrected

I guess nobody noticed, but in CNC and RA, the legs of infantry move way too fast. It should be ~100 Tick.

when building other buildings, construction yard crane should go slower, at ~100 tick.

Flame Tank gets FlametankExplode when it dies (big explosion that hurts nearby units)
