Revamp DSP Manager
Adds drawer navigation to the DSP Manager.
Drawer navigation is default, but it also allows to switch back
to the old view pager (tabbed) navigation.

It also allows to enable/disable drawer mode, enable/disable
tabbed mode and enable/disable the option to switch between
these two navigation modes.
