Create higher order components to load reset styles and set theme.

[wmertens]

The docs site shows that a small CSS reset is still needed: https://github.com/callemall/material-ui/blob/master/docs/src/css/main.css#L16-L27

Why not put this in a style tag as part of a SetMaterialStyle component?

This component could also load the theme manager in the context so that doesn't need to be done in the application code.

Wondering about this as well.

@wmertens I think that's a good idea. Recently there was a theme HOC created, so we could add it to that component. See #797

#797 has been merged. Now we have both a helper ThemeManager as well as a ThemeDecorator decorator.
