newRPL: design of soft menus

Off topic:

I just saw that hpgcc3 has a reworked website with the project of newRPL, I was updated up to hpgcc2. I mean, already having the possibility to run C on the hp50g is great, now even a better interpreter of RPL!

I know it changes a little, but Claudio, you did an amazing work, even more putting the code on well known repository sites (sourceforce & co)!
