Added Caps / Num Lock indicator to Awesome, included helper scripts

* New widget to Awesome main wibar, showing the output of caps_lock.sh
  (which returns valid Pango syntax)
* Included various helper scripts, used in some configs
* Modified theme border to 1px and my custom blue color

TODO:

* Get rid of Awesome's keyboard lag when executing arbitrary keymap scripts
  via io.popen (I guess there is a timeout somewhere to hack)
* Rebind the default run prompt, maybe modded a bit, dmenu_run is too slow
