dwm: More tags, killclient on Control-Shift-Escape.
dwm: Keys for shiftview() and tagrel().
dwm: Added remaining tags.
dwm: Disabled clicks on tag bar because they're broken now.

... due to commit 28672a7 in dwm-vain.
dwm: Added new mouse keybinds.
dwm: Reworked hjkl keybinds.
dwm: New killclient key was hard to reach on my netbook.
dwm: Named tags 1 and 2.

They are the only tags used in rules. As such, I think they should have
clear names.
