* Update borealis.
* Update libusbhsfs.
* Begin implementation of a DumpOptionsFrame class to display configurable options before starting a new dump process.
* bktr: rename bktrIsValidSubstorage() to bktrIsValidSubStorage(), use bktrIsValidSubStorage() in bktrInitializeCompressedStorageContext(), fixed a bug in bktrReadCompressedStorage() where Sparse substorages wouldn't be allowed.
