Allow the dry run mode

We'll need to support the dry-run mode of cucumber. This will be used for lots of things, but mainly to list the existing defined steps with the following command for example:

cucumber -d -f stepdefs

This will allow people to know which sentences has already been defined to ease the test writing. Thanks to Fabien Lydoire for this idea ;)

I already test this little "bad" patch to test it can be done and it works. We need now a "clean" way to deal with that dry-run mode.

Here is my patch :
