added a dependency to the service which probably doesn't need to be there actually...
fixed the way I wrote a function so it won't crash after being unable to get the ip address from that one site.
Merge branch 'master' of github.com:TheNotary/ipfixer_client
rewrote invalid_ip? function to use regex.  It seriously didn't function as it was written...
cleaned out tabs and converted to double spaces
stubbed out unit tests for invalid ip checker... that won't be used since I stole my validity checker from the web...
wrote tests on my regex, now I'm sure it works I guess.
commented a test
