Version tags need a 'v' prefix to work with Berkshelf

[Randommood]

Berkshelf uses a different tagging system. It would be lovely to have compatible release tags.

@Randommood I'm open to considering this, but can you tell me the benefit this provides? I use the following in a project that I just setup and it seems to work fine:

cookbook "postgresql", "~> 0.13.1",
  git: "https://github.com/phlipper/chef-postgresql.git"

Thanks!
