Create dedicated backup dialog.

The "Installation" dialog allows backing up the current installation by
creating a zip file from the .rockbox folder since quite a while. However, this
has the drawback that you need to update your build to create a backup, but
creating a backup might be desireable in other cases as well (before updating
themes, or just for backup reasons). Since the functionality is somewhat hidden
it's also not obvious to users such a functionality exists (most users are
likely to use the "Quick Start" instead).

Implement backup functionality as dedicated dialog placed on the Uninstall tab.
Rename the Uninstall tab to accommodate this.
