I fixed a couple bugs with pausing, added a speedrun mode and a cool combo counter.

• Added lighting. Yeah the whole game wasnt even lit.
• Jumping is now instant
• Takedown is now 1 hit the big guys for real this time.
• Fixed tab weapon menu ammo counter and add ammo counter on item on ground
• Camera speed is now a little smoother (maybe not, this has been a bug for a while)
• Minions now use the same shader
• Environment is now marked as static, should increase FPS... i hope
• Speedrun mode disables all the ""cutscenes"" and shows a timer in the bottom right.

Linux and maxOS build support is in progress, there are just a couple bugs that need to be addressed before I start releasing it.

Also i fixed that one area with the key. 

Screw keys.
