  Fixed gamecontroller database sorting script not sorting the whole database. The script was originally written for an SDL_gamecontrollerdb.h which had groups of mappings separated by single lines starting with a "#". This was changed some time ago to #endif/#if pairs. Because the script assumed only a single #endif in the whole file it no longer worked correctly and only processed the first group.
