Add JSON parse and encode function

[BaerMitUmlaut]

When merged this pull request will:

• Add a parse and encode function for JSON

Uses a shift-reduce parser, not too complicated. Handles all valid JSON, but will throw script errors with invalid JSON. Escaped unicode characters are not supported because I didn't want to write a hex to dec function.
Closes #1266.
