Title: Fix sidenav not allowing flex children

This fixes #734 which prevented you from aligning items to the bottom of a side nav because "flex" wouldn't work on child elements. The `display:flex` on `.md-closed-add` and `.md-closed-remove` also prevents you from seeing a pop from elements when you open/close the sidenav when you use `display:flex` on the open state.
