Card 101

- Added style for app-header (this includes the global action button) when clicked it needs to display a modal.
- Added the styles for toolbar, including folder navigation and the toolbar actions icons.
- Added some styles for responsive views.

@winkerVSbecks you probably have a better solution for this. I need to limit the length of text inside a button.
