Title: Custom validators

### Changes:
- Prevents multiple-submit on forms unless there's a validation error. Fixes DoSomething/dosomething#1907.
- Style "suggestion" validation errors based on "success" value, rather than having a generic "warning" style.
- Removes special logic I had implemented for "custom validators", instead relying on same validator function logic as everything else.
- Some other minor cleanups.
