[noise] Revision 31

[Trevor Perrin]

Published - https://noiseprotocol.org

Changes:
 - New pattern notation ("ee" instead of "dhee", first char is initiator always)
 - Remove "secondary symmetric key" feature
 - Added proper BibTex/Pandoc references
 - Added proper tables for patterns, so they pagebreak nicely in PDF

The html styling (css) could probably be better - (responsive for
mobile? better fonts and tables), if anyone feels like improving the
appearance.
