Added default commission request template to new users
Effect: When a new user is created (via sign up) they are now given a default
        commission request template, allowing them to be commissioned
        with no further setup
        This also gives them a base to work off of when they go to edit_template
This requires the users controller reading from a file, but it is surrounded by
exception handling code so it should be robust and give users an empty json template
if unable to read the file
Merge branch 'master' of https://github.com/japacible/commission-me into new_master
