Tweaked button shine
Fixed note height calculation
Fixed non-dynamic LESS color
Rearranged some menu logic
Added menu for user's blogs
Implemented tag searches + miscellaneous cleanup

* /api no longer takes a JSON-encoded 'data' parameter. Instead, endpoints
  describe valid parameters and then search for those in the POST data.
* /dash and friends now provide a single 'Washboard' JS object, instead of
  polluting the global namespace with a mix of all-caps and lowercase
  variables.
* /tagged/[tag] paginates posts correctly for both featured and regular tags.
