Sérgio Gomes f562f49d8a Makes typography definitions optional, through mdl-typography class.
Also adds mdl-base class, which is currently set to include just the
mdl-typography definitions, but will later be extended to include
other global definitions.

All demos, tests and templates have been updated to use mdl-base.
