* Thread-safe.
* Provides getter/setter functions for the data types used by nxdumptool's configuration.
* Each setter function writes the modified JSON configuration back to the SD card.
* Configuration is validated on interface initialization. If validation fails, a default JSON template is loaded from the application's RomFS and written back to the SD card.
Other changes:
* Implement directory creation.
* Moved more preprocessor definitions to defines.h.
* Replaced strtok() calls throughout the code with strtok_r() to guarantee thread-safety.
* Updated borealis fork (refer to https://github.com/DarkMatterCore/borealis/commits/nxdumptool-legacy).
* Updated NcaKeyGeneration enum.
* Commented out title task notification.
* Remove unnecessary instant view invalidations.
* NS application records are now retrieved using a loop.
* Fixed text alignment issues in RootView.
* Slightly improved gamecard notifications.
* Refocus logic now also takes care of updating Borealis' internal focus stack if a view has been pushed on top of the root view using a ListItem from LayeredErrorFrame.
* Further modifications to Borealis are used to store a pointer to the corresponding sidebar item in LayeredErrorFrame objects.
* The UI code now always uses C++-style casts.
* Git commit information is now displayed next to the nxdumptool release version.
* The applet mode warning is now displayed centered at the top.
* Title IDs in title lists are now displayed at the right of each entry.
* LayeredErrorFrame: both the error frame and the list are now protected instead of private, letting any expanded classes take more control over the them. SetErrorFrameMessage(), AddListView() and the class destructor have been removed because of this change.
* LayeredErrorFrame: removed views vector and simplified the list element focus check carried out before switching to the error frame.
