av2 singlepage + stuff

- Added single-page version of the Alta Via 2 pages, optimized for
  printing in A4 format.
- Added .noheadermd extension to build.sh (treated like .md, but
  without header and footer).
- Added versioning for css file.
- Resized some Alta Via 2 pictures for fitting in pdf page.
