add CBA_fnc_parseJSON and CBA_fnc_encodeJSON ports from ALiVE

[commy2]

When merged this pull request will:

• close JSON parse #1266

[commy2]

Current:

_hash = [loadFile "\x\cba\addons\hashes\test_parseJSON_config.json"] call CBA_fnc_parseJSON;

[_hash, "
    firstName"] call CBA_fnc_hashGet // " Jason"

So it has problems with white space apparently.

Baer wrote a parser that works better (at all?) compared to the ports.
