gravel 1.0.0-SNAPSHOT does not exist in the remote repositor

[aguizar]

The version of gravel indicated above does not exist in the repository. I'm reverting to 1.0.0.CR1 until the library is available.

My apologies, I forgot to commit this change last night before going to bed. Yes, CR1 is the proper version for Gravel.
