Fixed tanks
Fixes #5374
*fixes revolution

Because only one head is ever assigned before pre_setup (because gamemode code) it was constantly setting head_revolutionaries to 1, which failed required_enemies (which I forgot to change).

Now it will just assign three head revs all the time, but recind that status from some if needed once gamemode code figures out howm many heads there actually are. No one who gets unpersoned like this should ever notice that it had happened.
Oh right those are both lists
