Preparations for a 3.2.0 release

- Update the p2 task to use
http://download.eclipse.org/nebula/updates/nightly/latest
- Update the build to use
https://download.eclipse.org/releases/milestone to build always by
default against the most recent SimRel content.
- Update org.eclipse.nebula.widgets.grid.test to use bundle
org.eclipse.rap.rwt.testfixture optional to avoid forcing RAP into the
target platform.
  - I don't believe support for RAP/rwt actually works.
  - Also, this fragment isn't actually used as part of the build.
