[mapserver-dev] Release plans migrated to Trac

[Howard Butler]

To continue the ongoing migration updates, I have migrated the release  
plan documents to Trac.

http://trac.osgeo.org/mapserver/wiki/ReleasePlans

All of the other documents of the "development" section of the website  
are in svn, but it made a lot of sense to have release planning  
documents be part of Trac for the ticket and svn integration.
