expose separator color for theming + bug fix

I did a double take, apparently he messed up a copy/paste.

+     - `--line-uses-inside`, `-s` -- the line between the inside and outer ring uses the inside color for its color
   - All the colors have an alpha channel now. Please keep in mind that this was not intended when the program was originally written, so making things transparent that weren't before can make it look strange.
 
 - You can specify whether i3lock should bell upon a wrong password.
