Add support for BPS/BPM/IPS-formatted binary delta patches. BPS standardization edits. * Clean up headers. * Move crc32.c to /crypto/. * Rename beat.c to bps.c and move it to /system/ with the rest of the non-3DS file formats. Allocate memory for Source and Target files when possible. Last-minute BPS improvements. * BPS fails more gracefully on error, freeing memory and showing a more detailed message. * BPM no longer deletes the folder it patches to - that should be up to the user. * BPM is scanned before patching to figure out the total output file size for a more accurate progress bar. Add IPS support. 2018-04-11 11:30:43 -05:00			`// C port of byuu's \nall\crc32.hpp, which was released under GPLv3`
