Examples for the experimental features.

[Moderocky]

Description

To help give testers some initiative, I've created some example scripts for 2.10's experimental features (queues, for each loops, script reflection).

I've also tweaked an issue I noticed with queues (namely, you couldn't loop them as a variable since they looked like a single value). I think this issue is probably more widespread (any containerised value) but that will need investigating later.

I added a new structure specifically for examples: example!
Code in this structure is parsed (so examples would still report parse errors) but the code is discarded and never run.

example:
    kill the player
    teleport the player to {the moon}
    # Nothing here gets run

This can be used to set up little code snippet examples, without needing to create some involved structure.
The existing example scripts all have to be whole things (events, commands, etc.) and it can be quite complicated to make a clean example for some features. I'm hoping this will encourage some more introductory content to be made.

Nice changes, a couple things

Content seems okay. Seems like a few typos need fixed (test failures) (and Queue was throwing an assertion error? check logs)

Some indentation inconsistencies between files but looks good
