DR 126 mindtouch.db.exe tool has some confusing behavior

1) -f should not be used for dryrun, it is too similar to –force (--noop now)
2) when specifying a custom method (-c) it should not also run the update methods
3) Pass in the catalog to the method definition class so that we can log for the appropriate site id
