Modify at-full' and de-bruijn' overlays to color depth

Browse Source 
* avy.el (avy-lead-face-2): New face.
(avy-lead-faces): New defconst. Each element will be used to color the
corresponding depth.
(avy--overlay-at-full): Use `avy-lead-faces' to represent the current
decision depth. For `de-bruijn', prepend the old stuff, so that nothing
moves.

Fixes #53
