[NaCl Docs] archived security contest pages, converted to reST.

The security contest pages, including the legalese terms and
conditions, converted to reST.  NB: the numbering of the terms and
conditions in Sphinx enumerated lists differ in style from the
original, since we appear to have no control over whether roman
numerals, arabic numerals, or alphabetic enumeration is done.

I think this could be put under the publications and presentations
page as JF suggested, but I'll try that in a separate CL.
