Add three options: usesmallcapitalsintitle, usesectionslide and nototalslides.

beamerfontthememetropolis.sty:
- Remove "series=\scshape" for frame titles.

beamerthemem.sty:
- Add three options:
  * usesmallcapitalsintitle: print frame titles in small capitals.
  * usesectionslide: introduce a new section by an own slide.
  * nototalslides: print "#current/#total" slides per default.
    Disable this behavior by setting this option
