Use template support in wingtips, streamline configs

Uses template support in wingtips from https://github.com/PragTob/wingtips/pull/21

Breaks slides up into grouped, named sections, then updates config.rb and
tobi_config.rb to use those (with some personal modifications in each of them.)

What do you think @PragTob?
Love how you formatted this whole block by TitleSlide/minor slides etc.... !!!! :heart: :heart: :heart: 

such greatness!
