Subject: Add recents files to the document browser

The recents mechanism works like this:
Every time the file is opened, it saves that file to the shared
preferences set, by putting it in the first place, and removing the
oldest file from the list, if there are more than 4 recent files.

It also adds dynamic App Shortcuts if the device is 7.0 and above.

Edited the layout to add a new RecyclerView for recent items, as
well as the headers for both the recycler view's. Recent files
appear only if in home directory, below app bar and above the
file browser. This could be subjected to change in the future.
