Refactor color definition ; Cleanup colors once config is loaded

Browse Source 
Now use TermInfo feature detection instead of just distinguishing if
"$OS == FreeBSD". This will allow support for more terminal definitions.

Cleanup color variables (BLACK, WHITE, BLUE, BOLD...) once the config
file has been loaded as color variables are not used at runtime.
