Feature Request: Support re-orderable list property values in GameStudio

Is your feature request related to a problem? Please describe.
Currently Lists in the GameStudio editor are one and done. Once you add an item, its place is cemented and cannot be adjusted without removing and re-adding all items to the desired order.

Describe the solution you'd like
It looks like GameStudio at one point did support re-ordering (or attempted to) in ReorderCollectionItemViewModel, however, it is all commented out with "Fix Me".

I was not able to find any messages or issues on why/what was the original issue.

Describe alternatives you've considered
Alternatives are a code only approach where GameStudio doesn't matter, leaving the order as is, and/or manually adjusting it by adding/removing items.

Additional context
I've been messing around with it locally, but wanted to get some feels out on if anyone knows what the original problem was / why it was gutted.

Also does the Editor rewrite make this unnecessary / not worth pursuing at the moment?

• What are the use cases?
  Largely just an Editor convenience.
