Added cookbook name and version bump

Hello,

This pull request fixes cookbook dependency resolution using Berkshelf.

```
Fetching 'tomcat7' from https://github.com/jtalks-org/jtalks-vm.git (at master/cookbooks/tomcat7)
Ridley::Errors::MissingNameAttribute The metadata at '/var/folders/6w/gk5wvlvn13bd9g4vpk20yvrr0000gn/T/d20140408-47229-1tnf1cd' does not contain a 'name' attribute. While Chef does not strictly enforce this requirement, Ridley cannot continue without a valid metadata 'name' entry.
