* 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.
* Tasks are now immediately started by their constructor function.
* Events are now part of the class of each task type, in order to avoid instantiating each one of them and passing them as a constructor argument.
* GetTaskEvent() has been added to each task class, which returns a pointer to the private event. This will be used to subscribe Borealis views to a particular event.
* Title and UMS tasks now both cache application metadata and UMS device info using private vectors. Pointers to these private vectors can now be retrieved using public functions GetApplicationMetadata() and GetUmsDevices(), respectively.
* core: implemented SCOPED_TRY_LOCK macro. Specific functions are now using it instead of SCOPED_LOCK to avoid potentially locking the Borealis UI.
* UI: implemented background tasks for Borealis, which call functions that now use SCOPED_TRY_LOCK.
