Drawer : Add more option

[NgKhanh]

Pls add more option for Drawer such as:

• open/close status
• left/right direction

[tleunen]

Currently, the drawer is part of the layout component, if we add these options/props, it would require a way to communicate between the drawer and the layout, or simply have them on the Layout component.

I know the MDL team will work on a better layout/drawer system in their V2, and I'd like to also improve all this in our V2 (related to this #295), but currently with the state of v1, it seems hard to achieve... Unless someone has an idea and I'm all ears!
