Create a Tag

[Valerie-Freeman]

As an author I would like to be able to create a new Tag so that I can better classify my posts.

Given an author is on the Tag list page
When they select the Create Tag button
Then they should be directed to a form in which they can enter a new Tag name

Given an author has entered a Tag name
When they click the Save button
Then a new Tag should be saved to the database
And the author should be directed to the Tag list page
