Bunch of changes.
* Updated NCA structs (including NcaSparseInfo). * Changed the way NCA header + NCA FS header decryption is handled. * Changed the way the NCA encrypted key area is handled. * Unified hierarchical patch generation functions. * Updated PFS, RomFS and BKTR functions accordingly to reflect NCA handling changes. * Logfile path is now relative. * Gamecard initial data lookup code now uses the initial data hash from the gamecard header (a tad bit slower, but way more failproof).
