- removed most of lodepng's optional features
- lodepng now uses the already existing CRC32 code instead of using its own copy
- fixed GIC interrupt priority
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.
