Fix for urgent window colour and $txtacolour being too light to see against default urgent background colour.

Switch to mod+q not toggling but now creating a split tabbed container from current window.  Just my personal preference (trying out).  i3Status changed to give more info for disk usage status).

Restructure to be repo for various config files.  Added config files for compton, dmenurc, dunst, i3exit, i3status, and rofi (theme) - mostly origs (for init).
