Fixed a bug when marking the capture password, saving and unmarking the capture password, the attribute does not comeback and the password will never be captured again for this template.
More cleanup - changing *all* API errors to be returned via JSON
Fixed bug where /api/pages/ was not csrf exempt
Changed db column/table names to be more user friendly in the case of acronyms (Id, SMTP, etc.)
Additional cleanup, documentation
Changed return values for /api/templates and /api/pages to return empty array [] if no results (like /api/campaigns was already doing)
