Support highlighting fill-column overflows

Browse source 
This was previously semi-supported. There were two problems, however:

1. My fill-column value of 80 got out-of-sync with my white-line-column
   value of 100.
   Solution: globally define wpc/fill-column, set that to 80, and
   consume the new const in my config.

2. Nothing was activating whitespace mode.
   Solution: add whitespace-mode to prog-mode-hook.

This SO answer helped tremendously:
