First stab at MD text buttons
These buttons are implemented as a new class separate from LabelButton, which we'll need to retain even when MD is default for certain use cases such as the bookmarks bar.
This new class is used on MD infobars.
This first rough cut doesn't support
a) different button attributes that might affect rendering such as being a Call to Action or default in a dialog. TODO: estade
b) hover or press effects. TODO: bruthig
c) images on the button. I doubt we'll ever want to support images on material buttons, but it's possible we'll decide to add them later.
