Add JSON File Format to Macro Editor

Hello,

The Macro editor has been out for a while now, and there are some interesting workarounds and more complex scripts than ever imagined.

But at this time, the only file format allow is .js in the editor

To be able to allow for .json or .txt would be great to create an area for us to store information in a clear, readable format and allow the community the ability to take our scripts to the next level.

At the moment, we can replicate this in .js format, but it does leaves room for error and mistakes.

.JSON could simplify this process greatly.

Thanks,
