[threeten-dev] Schedule after M6

[Roger Riggs]

fyi, the dates for Threeten work leading up to M7  - Developer Preview

  * Feb 4 - final API freeze for review
  * Feb 13 - last day to push into the OpenJDK TL repository on the way
    to JDK 8 repository
  * Feb 21 - M7 build completes

The Public Review of JSR310 should be based on this milestone also.

The milestones after M7 are identified primarily as bug fixing and test 
completion
but if necessary can resolve API issues raised during JSR 310 public review.
