Title: if default locations are specified then a downloader will only use those

this will fix a potential issue where a cookbook is not found at the default locations
provided by the user and then attempt to find them in the exact location if the downloader
happens to also have those locations set as it's default, defaults.

also good practice to let a user decide not to go out to Opscode...
