[navigation-timing] domLoading is deprecated

Following the discussion in
  https://github.com/w3c/navigation-timing/issues/13
and
  https://lists.w3.org/Archives/Public/public-web-perf/2015May/0028.html

I added the following note to domLoading:
[[
The domLoading attribute is deprecated and may be removed in future 
versions of this specification. Due to differences in when a Document 
object is created in existing user agents, the value returned by the 
domLoading is implementation specific and should not be used in 
meaningful metrics.

Todd indicated that Microsoft Edge will change its behavior in the 
future to return the same value as responseStart.

Feedback is welcome this change causes pain.
