nano: provide nano-full with most features enabled

Provide a new variant, nano-full, that enables almost
all functionality of nano. Only libmagic file type detection
has been left out.

Ship with a minimal /etc/nanorc that the user can modify.
nanorc documentation at
https://www.nano-editor.org/dist/latest/nanorc.5.html

Provide color highlighting for the uci config files.
