This makes it so that `make -C doc` works to build all of the docs in a single command.
there are still a few problems with this:
1. the build does not fail if the correct fonts are not found
2. the images are only generated via the makefile, so trying to build the docs by other methods won't work
- remove quick draft images
- push plain screenshots and separate plain text svg files
- Update label content based on user feedback
- Cleaner label layout
- Use same fonts in labels as in text + better scaling
- basic automation of inkscape in travis; this probably needs some work. It should at least be moved into the make doc instead
