support more games and QoL improvements

• numpad keys are now detected as regular 1-9,-,+ keys (if numlock is on) in consideration of various foreign keyboards
• added 32/64 bit version to about menu
• added "open settings folder" option
• default hotkeys are now CTRL ALT 1-9. SHIFT removed since it conflicts with numpad.
• Windows XP support is discontinued.
• improved support for various games like path of exile and overwatch and apps like bluestacks
• changed window detection from the foreground one to the one at the cursor. hopefully this fixes issues with various overlays getting in the way.
• possibly fixed mysterious D: drive access. thx shagv@reddit for the find :)
• fixed handling of game using an invalid cursor. fixes stellaris.
