Fix for #20 - Add Support for CLI options

A simple fix to extract additional command line options from the arguments passed to the `cucumber` task that are not already handled by the plugin.

Adds support for:
* `--dry-run`, `-d`
* `--strict`, `-s`
* `--monochrone`, `-m`

Also updated version for Scala 2.10 to the 2.10.0 final from the RC2
