draft-nottingham-site-meta: put key bit (/.well-known/) in the abstract

[Dan Connolly <connolly at w3.org>]

I just started to summarize the draft for another audience (www-tag),
and the most relevant bit I found was:

[[
   ... this memo defines a path prefix for these "well- 
   known locations", "/.well-known/".  Future specifications that need
   to define a resource for such site-wide metadata can register their
   use to avoid collisions and minimise impingement upon sites' URI
   space.
]]

Please add that to the abstract, so that this abstract
may better "act as a stand-alone entity instead of a full paper"*.
