Merge branch 'master' of https://github.com/rasputine/pynginx
Added nagios commands.
Nagios Load Balancer service status check

running `nagios check` command will return a single response with
an error code to set the service status.
States are mapped to responses in the nagios.py file ATM until a
better setup can be done. lines 22-24.
Small improvements to nagios check

Corrected error with deafulting to nagis check if second nagios command not given. Previously would throw index error, now should skip the list entirely.
Corrected exit code bug, exit code 0 was erroneously defined as a string instead of a number.
Set nagios report to print to single line.
Changed response format for nagios check
Changed order of response message

from eg "xml web1 down" to "web1 xml down"
Improved logic of the nagiosCheckLB function

Removed a bunch of redundant code and streamlined the logic substantially.
