Filetype setting for man pages on FreeBSD
add justinkb to CONTRIBUTORS
release 1.7.8
change vimcat from /bin/sh to /bin/bash

The script uses bash specific features, and until I can rewrite it in
bourne shell the shebang needs to be /bin/bash for systems where /bin/sh
is not bash.
Reset fg colour if no fg is set
use env bash not /bin/bash for vimcat shebang

Also use $0 for error message.
release 1.7.9
