Reset Tags

Adds a script that will remove all version tags by doing the following:

1. Remove all tags beginning with "v" from remotes
2. Remove all local tags
3. Fetch tags from all remotes (which now do not include version tags)
4. Add an initial v0.0.1 tag to local and push it to origin and pantheon

Expectation is to run this script as a subsequent action of the clone script to reset version tags for each new project.
