add completion popups for new json functions - #2

Hi !
Thank you for your PR !
I didn't know functions could return Jason data? Is it a new feature of nwn1:ee?

Also the jsson addition should be before the struct (struct is a bit special because we need to match the struct keyword followed by a struct name)

Like so:

    nwn_types = r'(void|string|int|float|object|vector|location|effect|event|talent|itemproperty|action|json|struct\s+\w+)'

there ya go -- didn't realize exactly what the \s+\w+ were

yes it's a great new feature from the lovely Beamdog, the json type supports all the native types of nwscript, but can also do everything json can normally do like create json objects, arrays, get the list of keys, etc; we can import json from a template too and make .gff edits to things like .utf creature files from directly within nwscript, and then spawn the creature in with the designated changes! really wonderful

your project is quite literally perfect for autocompletions and hint popups, and works spendidly on the new ST4 :)

I wish we had the same json type in NWN2 :(

Thank you for your PR ! I'm glad to see some NWN1 people use my plugin, given it was originally written for NWN2
