interim release 742

This release fixes a nasty bug in List that Lenard ran into.  It also has a
several new features since the last release.

Warning, if you use the new @ debug feature and forget to start Prothon with
the -d@ option, it will give a quick parser error and kick you totally out
of Prothon.  I will fix this asap but beware for now.
