* Fixed a bug in the option parsing. When no options (or unknown options) where
presented it was not properly defaulting.
* Fixed a bug when incorrect options where given. Apache Commons CLI fails
entirely when it is unable to parse an option. This means we cannot get the
`--dir` option and we default to the program's working directory. When running
on Nailgun this is not the desired behavior and can cause pit to look through
a very deep file heirarchy to find issues.
