New options to run():
  createCTDEcatalog=TRUE
  background=FALSE

The background option is commented out... but the RJSONIO warning message is probably irrelevant.
Bumped version...
I removed the dependencies on shiny and shinyIncubator. Sure enough, the warnings about RJSONIO go away... but they don't seem to matter anyway, and these packages are needed.
Removed misleading startup message.
Replaced use of "cq" since we don't want dependency on mvbutils.
