Implemented the design and fixed the ons.notification.* methods.

I'm not sure about the classnames:

Right now it's like this:

alert-dialog--material-title--one

But I think this is better:

alert-dialog-title--material--one

Or even this:

alert-dialog--material__title--one

@argelius
hmm... "alert-dialog--material-title--one" class name looks strange.
Could you fix this naming as you say?

[argelius]

@anatoo I changed the class names.

Please merge if there are no problems.
