* Clean Exiting was improved by implementing a robust system for when to abandon clean exiting and simply restart the process alongside moving clean exiting to the background when the application is quit by using the back button
* Audio is now automatically paused whenever the application is moved to the background and automatically resumed when it's brought to the foreground
* The system language setting had several errors and inconsistencies which have now been fixed, it's been brought more in line with HOS language (Albeit not entirely due to no region setting in Skyline)
* Fix a bug with `ThreadLocal` where the atomic `list` pointer was uninitialized resulting in a `SEGFAULT` during the destructor
With `RecyclerView` being used rather than `ListView` or `GridView`. It's now possible to display the items in a flexible manner and so support for a grid view in addition to the already existing list view was added in.
This commit adapts the C++ backend to the Kotlin frontend by moving to usage of file descriptors and, provides an interface to access frontend code via JNI which is used to check the state of the activity and catch events such as surface destruction. In addition, this commit fixes some minor linting errors and changes the CMake version to 3.10.2+.
