LiveCode library inclusion in Standalones...

As a test I added a "dummy" handler to the card script of my mainstack:

on livecodeLibraryLoader
  -- This handler is never called. It exists to contain code that will
be detected by the IDE's Standalone Builder
  -- to ensure certain libraries are included in the standalone.
  -- ensure inclusion of libURL (Internet) library
  put url tSomeURL into tSomeVariable
  post tSomeData to URL tSomeURL
  -- ensure including of ...
end livecodeLibraryLoader

And now libURL gets included using auto-detection. So it look like (at
least in LC 6.7.x) that autodetection only checks the Mainstack and not
substacks? That seems like a bug, but I am not in a position to test in
LC 7.x or 8.x to see if that is also the case in those versions
