Adding 'Go to Definition' proof of concept.  Needs a bit of cleanup, I dev tested this via the palette menu, not via F12 shortcut key.
very broken autocomplete
corrected line/col
working but sync autocomplete
not using http-sync
merge master
merged master
merge with master and max 1000 items in console output
converted the sync autocompletions to async using autocomplete-plus-asyc
