update to v60 - mainly suppression and some bug fixes for companion

Major update to how suppression works. All weapons will suppress enemies when you shoot at them, more elite and armored enemies are harder to suppress, but rookies (the grey enemies in the early levels) will definitely keep their head down.

The mg has especially high suppression, so now it is absolutely deadly against enemies in the open and will suppress enemies in cover to a point, where your second character can flank under cover fire. Something I always wanted to have in an action game, allowing for proper tactics.

Let me know if it makes the game too easy or slow or if it's actually adding to the tactical aspect and experience.

Also now most of the sprites are exposed for modding. As well as the weapon stats.
