Title: Some minor additions

Docblock comments had incorrect param/return values indicated.
Version::getVersionsTable() I made default table name come from the bundle, or if nothing else use the static class var.
Also added Version::addIfChanged() method to save the model only if it exists and if an attribute has changed since last time the model was saved to DB. (This prevents the extra hit on DB used in Version::add() in case of identical object)
