Proposed Schedules for next few releases

[Kate Stewart]

Dear Release Team Members,

   Based on the developer input gathered by Alison earlier (Thanks!),
and other feedback received through this cycle,  I've updated the 
straw man proposals for the next 5 releases.

Highlights:  even them out from 28/24 weeks to 27/25 weeks.
Move Feature Freeze after Alpha drops and even out its timing
a bit too.

Please review and let me know if you can see some factors overlooked, or
interactions that need to be considered.

At UDS-P we'll be doing a final review of the P Release Schedule
milestone dates and freezes, before removing the **DRAFT** from P
Release Schedule.

Thanks, Kate
