newRPL - Updated to build 1510 [official build remains at 1487]

[Gilles]

Hello, I have some questions about the CRLIB command:

1/ When the name of the command is long and truncated in the menu, it is useful to display the complete name of the command with the "help long press". It works like this for internal commands. But is it possible to do it in a library?

2/ It's great that auto-completion works with add-on libraries. Cheer!

3/ Is there a build 1497 ou 1510 for Windows ? I dont find them and I would like to use the FORUP and FORDN loops to avoid some tests.
