* 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.
Also increased the USB timeout again, since 1 second seems to be too low for gamecard transfers.
Big thanks to Whovian for helping me format that long system title list.
