Clear the console-abort flag upon return from executing a JS or Baja module.

This solves the problem of a JS-external program (e.g. SyncWX) being aborted
at a pause prompt with Ctrl-C or Q and that abort status propagating back to
the external program's menu. If there is a module which needs to propagate
the console-abort status up to the parent(s), then this could introduce a
problem. We'll see.
