- Fixes VUFIND-1214.

- Fixed captcha check in password recovery to not lose track of the auth method and user to recover if captcha check fails.

* Refactoring to shorten newPasswordAction().

- Slider handles to brand-primary
- Fix slider handle miscolors in SCSS

- Use jQuery to handle data attributes (needed for IE 9/10).
- Fix issue with all IE versions where Recaptcha dialogs don't accept any button presses.

- Use the tag_id instead of a hard-coded 1 as the is_me value; this is simpler and still works because all the template cares about is checking for non-null values.
- This works around a problem in some versions of MySQL where the hard-coded 1 was causing invalid results to be returned.

Fixed an issue where the login dialog breaks with ChoiceAuth if CSRF check fails for any reason (like session timeout).

Encode the username, so spaces in the username don't throw an error.

- Was out of sync with actual configuration.

- Use a timestamped init function name in Piwik tracking and load the tracking js only once. Fixes an error in lightbox and record tab tracking (Piwik logs to console: "A siteId must be given to add a new tracker").
