Switch back to awesome, again

- Honors sizing hints
- Interactive widgets (not necessary, just handy sometimes)
- Can reproduce favorite widgets from i3wm... with time
- Title in status bar
- Dynamic layout (can be handy, not necessary)
- Menu (mixed on utility of this for me, but may be handy e.g., for Fallout or other games)
- Still need to figure out:
  - Compton w/glx backend
  - Floating popup sizing, e.g., for prefs in various apps
  - A good look for the awesome bar
  - Other stuff
