HelpDesk-urls moved to the non-private help-desk-urls.ss so other collections can refer to them.
Fixed a few broken links in the "About DrScheme" dialog.
svn: r7230
Most non-manual help desk pages are now in /help/servlets/home.ss
Servlets are now x-expr based instead of string based.
See instructions in /help/launch.ss if you want to try the online version.
