========================
- deprecate shell_tinymce_2(), "hr" already available in wp 3.9
- remove "underline" mce button in shell_tinymce_1(), already available in wp 3.9
- in shell-open-sans, use all font variation, and remove "http:" for compat with "https" protocol.
- add/register shell-merriweather google font.
  now we have serif (Merriweather) and sans-serif (Open Sans) google fonts to use :)
- deprecate shell_get_menu_location() and add shell_get_menu_name( $location )
  for a better function name.
