Access private fields within doPrivileged
RamUsageEstimator/StaticFieldsInvariantRule do some inspection of private
members... but this requires `RuntimePermission("accessDeclaredMembers")` to do.

It would be nice to just grant this to the randomizedrunner jar.

Add an example that runs under securitymanager. It like a "test" that no strange permissions are needed.
Its build sets properties for the URLs of randomized-runner and junit4-ant jar files,
this way test-framework jars can have different permissions than test classes.

As a first step, the suppressAccessChecks permission (pure evil) needed by the gson serializer
is encapsulated within an AccessController block, and only the junit4 runner gets this permission.

clean up more setAccessible

link into POM and fix java 6 compile

Break out runtime permission and improve testing
