Title: Changes to the menu-icon

* Created mixin in `_global.scss` for called `hamburger` to easily create menu-icons.
* `@include`d mixin in `_topbar.scss` and `_offcanvas.scss`.

You might need to pull this down for testing. The amount of testing I have done is just using CodePen and it looks fine there.
