Making progress on shampoo zip dump options.  Currently downloads a zip, keeps a copy of that zip in a backups folder, and unzips.  Not yet download media if mediaOut exists.
Now accepts zip dumps, which unzips the dump and will save media locally if the correct option is set in the grunt config.
Moved domain over to shampoorc.
Updated docs.
Merge pull request #2 from handlebarcreative/master

Added zip downloading/unpacking functionality.
