* Added a function to write re-encrypted NCA and/or FS section headers. Getting ready to re-implement NSP dumping.
* Added more CNMT XML fields (thanks 0Liam).
* Updated my to-do list because I'm dummy.
* Added 'encrypted_header' members to both NcaContext and NcaFsSectionContext. In-place re-encryption isn't desirable in this case.
* Fixed FsAccessControl-related type naming for ACI0 blocks.
* Improved patch and add-on content title ID verification against a base application title ID.
* Implemented linked lists in TitleInfo structs, which make it easier to deal with multiple patches / add-on contents belonging to the same application.
* TitleApplicationMetadata elements are retrieved with titleGetApplicationMetadataEntries() and used by the UI to display title entries. An 'is_system' filter argument is used to determine which kind of metadata should be retrieved. These are ordered by ID (system titles) or alphabetically (user applications) using qsort().
* Added TitleUserApplicationData struct, which is populated when an user application is selected.
* Tweaked titleRefreshGameCardTitleInfo() behaviour a little bit. Now returns true whenever there are title info changes, so the UI can reload the list.
* Temporarily commented out title info logging from titleInitialize().
* Fixed decrypted key retrieval from the NCA key area for patches with titlekey crypto removed.
* Implemented a very small menu to select a title to dump.
* 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).
* Codestyle fixes.
* NCA contexts for NCAs with titlekey crypto will now be generated even if the ticket can't be retrieved, in order to be able to use ncaReadContentFile() with them.
* Moved aes128XtsNintendoCrypt() out of nca.c.
* Updated disclaimer in all source files.
* Improved signed payload (certificate, ticket) handling.
* Prefer strlen + strcmp over strncmp whenever possible.
* Simplify header file inclusions in source files.
* Simplify background gamecard thread logic.
* Properly close keys file handle if there's a key parse error.
* Update NcaKeyGeneration enum.
* Small changes to save.c/h.
Will probably have to revert some USB changes...
