Title: List plugins embedded in non dedicated gem

It looks like it was easier than I though !

this change includes in the "guard list" output guard plugins which are not in a "guard-xxx" gem by looking inside the gem folder if a "lib/guard/.rb" file is available.

I only updated the code for rubygems 1.8.0+ since I am not sure about the api provided below.
