Works well after some rework

Only needs the mysql command line client, which is nice.

Needed some rework to work well, new version here:
http://pastebin.com/jkzC8pDe (full)
http://pastebin.com/dybGAjzg (diff)

Problems fixed are:
– Connection failure not handled at all
– Error messages from mysql not captured
– Garbage output when called without command line arguments
– Does not work at all because of use of “==” bashish, despite calling /bin/sh
– cut is in /usr/bin, not /bin, at least on Debian/Ubuntu

Thanks for the plugin!
