[FEATURE REQUEST] New bottom navigation bar

[davigonz]

Since #2742 is a huge task, we have to split it up and go step by step, delivering changes that users can see in a short-therm.

The first step would be creating a new bottom navigation bar for moving between Files, Uploads, Av. offline and Shared by link options, being more accessible for the users than the current location of those options in the side menu.

Therefore, Files, Uploads, Av. offline and Shared by link options will be removed from the side menu and reallocated to the new bottom navigation bar.
