Command line arguments should be smarter // canonicalise hostname

[electronicmax]

Should make setup.py runner more robust to accidentlaly putting the url in or either that or return with an error.

e.g. 'python bin/server.py indx http://indx.local:8211'

should automatically be interpreted as

'python bin/server.py indx indx.local'

OR should return an error saying hey dont give me the full URL man.
