- Created .gitignore file within the template directory. I believe
that /this/ repository should not know about them but the
new_beamer_presentation should export these so that we don't have to
create a new .gitignore file from scratch every time we create a
presentation.
- moved over to the new notes format (requires the new version of pdfpc)
- pre-process the logo.pdf instead of doing it in the makefile
- addes new support for putting the slide revision (from git) on the
first slide
