Title: Add 'menu-left-open' and 'menu-right-open' classes

When opening a left side menu or right side menu, toggle a 'menu-right-open' or 'menu-left-open' class on the `ion-side-menu-content` element.

This allows for custom styling of the content pane (for example; show a dark overlay) when one of the menus is open.
