Xbox controller mapper

For some peculiar reason Doom 1 & 2 implemented in Doom 3: BFG Edition don't come with an option to remap gamepad controls. Alas, changes that I introduced in native config files didn't take effect after I run the game. Moreover, I was astounded to discover that my favourite gamepad mapper is paid software. Strange. I thought to myself that duplicating it's core functionality would fit my skill level just perfectly and I decided to write this utility. I should probably stick a note somewhere that warns me of starting the next "weekend project that would require me just one day to finish".
