Added a File->Run menu with a sub-menu of JSexec scripts that may now be easily

run by a point-and-click sysop. :-)
I have the beginnings of a run-any-JS-mod sub-menu item, but still need to work
on the prompt/selection of the filename to exec.
Native sbbs cmdline utils could be invoked via this menu option too (in the
future).
First COVID-19 deaths reported today in my home county. :-(
