[noise] Revision 27 (cosmetic)

[Trevor Perrin]

Fixed a typo, spacing, and sublist indent issues.  New docs on website:

The WhatsApp thing is some nice attention, but we need to capitalize
by offering people a good selection of open-source libraries.

I'll be working to improve my "screech" library.  I'd encourage others
to help review and improve the existing libraries and write new ones
(C and Java particularly needed).

Jonathan and Alex have done great work on test vectors and a test
vector format, so hopefully we can put together documentation of the
vector format, and an extensive library of vectors, soon as well.
