Added a new button to add custom skin compatibility to combine soldiers.

Repacked a custom soldier model to make custom soldier replacements compatible without using a separate map.
Finally, right?

Restored combat soundscapes, they should change based on amount of combine killed.

-Added back dustoff points for dropship soldiers, console shouldn't weep and cry that they are missing now. Potentially fixes combine not leaving the dropship too, who knows.

-Made the Automatic Wave Control a lot more sensible, no more enabling buttons while playing and are instead just enabled at the start and spawns special units when ready.

Fixed a lua error pertaining to a certain secret.

Fixed a button breaking in the spawn room after pressing it once. (Thank you Adler7ph)

Removed left over code in lua script that made hunters do a lot of damage. OOPS

Updated the ammo script to have a minimum clamp at 1 instead of 0. Should let you get ammo for the RPG and anything else that has a magazine size of 0(for any cool sweps that have large ammo pools but no magazines, sorry, you only get 1).

Fixed the kills per wave option not working after changing the value once.
