RPL emulator for the prime

[ji3m]

Please see later post fr updated version

I did some intensive work last year to create an rpl/rpn mode for the prime. With recent prime updates some errors occurred which I have fixed.
Its just an experiment but performs as well or better than go49g on my phone. There are two files which need to be sideloaded to the prime with a good text editor.
The file rplinfo.txt is the documentation as it exists.
