Bug fixes

Fixed missing \n at KEY_1 causing KEY_2 to be commented out
Reduced delay of key input to 30 ms instead of 100 (this is faster but
it may misstype as its using serial, but worked fine when i tested it a
few times).

Added REPEAT command convertion from Twin Duck Firmware. (if a script is
using this it will create a for loop and repeat the last command).
This should work with repeating string input (not tested).
Added missing keys ? + and \
Fixed error with WINDOWS/GUI conversion, needed LEFT or RIGHT GUI key.
