Use of incorrect cookbook version format prevents berkshelf from being able to install the cookbook

[brenttheisen]

Getting the following error while attempting to use berkshelf to install this cookbook. The reason why is the current version of the cookbook is 2.5.0.pre when really it should be 2.5.0-pre in order to conform with the Chef cookbook versioning standard (see this Berkshelf issue).
