Bug fix on mobile that was displaying the button on a new line.
Smaller input/button sizes to win some space for breadcrumb nav.
Vertical alignment of search-form.
— Layout
* Create html templates to print breadcrumb's and submenu's lists.
* Remove ‘o_main_back’ ( no longer needed)
* Minimum mobile support for submenu. Note: The default website submenu
should be refactored in order to support mobile by default
— Style
* Create a less mixin to handle all doc’s dropdowns
* Add a specific style for breadcrumb when it’s placed inside the
submenu.
