Some bug fixes for the most common problems that aren't hardware or driver related.

• 4k Resolutions supported in Video Settings.
• Optimized Trigger Area in Hold mode.
• All Ingame Music should now peak at the same volume.
• "Needs More Gun" Achievement should now unlock reliably.
• "Stop Touching Me!" description now matches unlock conditions.
• You now have an option to launch the game in Windowed mode.

I've also changed how the Redists are handled to use Steams newer system. This is the first time I've used this system so I'm not sure what issues it may have. Hopefully none. The one thing to keep an eye out for is if you have to agree to a UDK EULA when starting the game. In theory this shouldn't happen but if it does please let me know.
