Configuration works mostly identical to previous state. Some exceptions:
- Minor changes in tag names (removed unicode symbols), as they are now
referenced by name in the rules.
- Calendar module is not yet ported and not loaded.
- Scratch terminal on F12 key currently moves to bottom of the screen after
first opening. Probably will be reimplemented using the new extended
awful.spawn API.
- awsetbg util writes different wallpaperrc (preexisting wallpaperrc is ignored,
as the filename now includes .lua)
