feat: Sort notes and folders in recent and browse pages

[Edgiest05]

Introduced a button SortButton located at the top-right of the UI in recent and browse pages (near the syncing one):

When pressed it shows a dropdown for a predetermined selection, provided in the static class SortNotes.
Such selection is preserved as a preference and is kept on app restart.

Sdk version change is not related to my own implementation, but instead is a workaround to compilation errors that made it impossible to test on android emulator.
