JSON chat support

[TheDGOfficial]

Is your feature request related to a problem? Please describe.
The skQuery's JSON expression is great, but it has problems and not directly integrated into Skript. There is a JSON-chat system in the new Skript eco-system, in the SkriptLang fork, dev27+ versions.

Describe the solution you'd like
Perhaps we can also integrate it to the LifeSkript, we are currently using skQuery's system but the JSON-chat one is directly integrated into Skript, and it works flawlessly.

Describe alternatives you've considered
We can also use skQuery's thing or copy it into our fork and fix its problems.

Additional information
I don't want to create a non-backward compatible Skript version, so it should NOT include the latest security fix where if the message contains an expression, variable, chat color or JSON it must be externally "colored" via the colo[u]red %strings% syntax.

The JSON one, of course, a security risk because the user can add a command to a message and this dangerous, but the color ones don't. We can always use the uncolored expression to remove colors.

So we should use another effect or mark pattern (e.g send JSON) that overrides skQuery's thing.
