New Pledge: Validate submitted form values and generate a draft pledge post (#35)

Browse source 
Ensures that a submission to the new pledge form has:

* A unique email address compared to existing pledges
* A unique domain in the URL, compared to existing pledges
* Has at least one valid contributor listed

Error messages when one or more of these conditions isn't met are descriptive so that the submitter can correct the issue.

Fixes #15
