Update Class Versions of classes impacted by ROOT 6

This pull request fixes most (perhaps all) ROOT6 relval errors of the form:

 The StreamerInfo of class MyClass read from file MyFIle.root   has the same version (=10) as the active class but a different checksum.

The classes in question have different checksums in ROOT 5 and ROOT 6 for valid reasons.
This pull request updates the version numbers for these classes.  Because edmClassVersion is currently disabled in ROOT6, it is non-trivial to get the checksums for ROOT6 and guarantee that they are correct..  Therefore, "999999999" is used as a placeholder for the checksum in the ROOT6 version.  When edmCheckClassVersion is turned back on, each instance of "999999999" can then be easily changed to the correct checksum.
