Stretched resolution fix

We've returned feature that was accidentally removed in last update - stretched resolution for Aim Hero. Even more: now you could set all parameters inside of the game using Fullscreen Mode dropdown and Use Custom Resolution toggle. - Exclusive Fullscreen: means game window will try to fill whole screen and will stretch if its not fit correct. - Fullscreen window: means game will fill whole screen, but if its resolution is not fit correct - game will add black bars on sides. - Windowed: means game will be windowed with setted resolution There could be issues with setting game to Exclusive Fullscreen mode, but it should work correct after game restart. Also please remember that screen stretching could not work without some graphic cards settings. Please continue to post your bug reports in the «Bugs or Glitches» of the Community Hub.
