BUGFIX Don't create new version on related VirtualPage records in SiteTree->onAfterWrite() when the write was triggered through writeWithoutVersion(). Use a new $_nextWriteWithoutVersion flag replacing the -1 Version number for this purpose (AIR-97)
This solves a bugfix when calling singleton($className)->summaryFields() and Versioned kicks back. It is needed to by the GridField functionality to get default columns to show.
This is due to DataExtension calls ClassName::extraStatics() when calling ::load_extra_statics() statically, we need to pass in class and extension.
