Burnin' Rubber 4 - 1.3 update

-----------------------------------------------
-- Burnin' Rubber 4 Standalone v1.3 / Game v2.3
-----------------------------------------------

* cleaned up some code/setup concering the Win10 fix - it should be easier and with less issues now
* implemented fix for centering window on multiple monitors
* implemented basic Gamepad controls - See Gamepad.txt
* implemented 4k resolutions - UNTESTED try it out! Does it work? Great! If not - too bad :(
* redeployed on Itch without the installer - this should work better if you use the Itch app (which we recommend)
  The previous 1.2 installer is still included though - you can find it at your Itch game library folder.   Look for BurninRubber4 then for Installer1.2
* update footer text ;) 
* new icon ;)
