The index range check in R<>R was faulty, allowing a row index equal to the number of rows + 1 to be used, which in turn would cause memory corruption. Fixed.

When renaming the currently active state, the state name was not updated in memory, with the result that upon exit, the state would still be saved under the old name, and at the next launch, would also be loaded under the old name. The net effect of all this was that instead of ending up with a renamed state, you'd end up with a copy.
