* Ported the logfile handler from libusbhsfs, with some slight modifications.
* Rewrote hash file system handling from scratch. I had been wanting to do this for some months now, it's a lot better now.
* Code cleanup.
* Temporarily changed tracked libusbhsfs branch from main to dev.
* Minor improvements in ums.c/h.
* Refactored nsp_dumper_sd into nsp_dumper_stor - now capable of dumping NSPs to a mounted partition from a UMS device.
* Fixed utilsWaitForButtonPress() when no button mask is provided.
* Refactored utilsGetFreeSpaceFromFileSystemByPath() into utilsGetFileSystemStatsByPath().
