Various tweaks for v0.0.3

- Bumped version number in bower.json, and dynamic-forms.js DocComment.
- More clarity for arrays being a valid option for a template.
- Point to GitHub instead of BitBucket as the default repo, since more users are on GH.
- Clean up indentation in the demo files.
- Reorder new sample fields in the demo templates for consistency with existing ordering
  (alphabetical in form-template.js; alphabetical within control-type groups in app.js).
- Added comment in app.js about the need to update `isOn` and `isOff` values in 1.3.x.
