Maya Exporter: Export Selected, Nicer JSON, default extension

[ascloutier]

I’ve added a handful of improvements that I think will really help people trying to use Maya with 3JS:

1. The current plugin will only perform an “Export all” regardless of what you select from the menu in Maya. I have fixed that so you can now “Export All” or “Export Selected”. Export all sill merges geometry rather than exporting a 3JS scene, may fix that in the future.
2. Updated the default extension to be “.json” rather than “.js”. This is more in-line with 3JS and the other exporters.
3. I pulled the JSON encoder from the Blender exporter and integrated it into the Maya one so that each item in the ups, faces, vertices, etc arrays are no longer on a separate line. Makes the file much easier to read and debug.
4. Turned off sorting of the JSON output. This is more of an opinion, but I didn’t feel like it helped the output at all.

The Maya exporter is still not in-line with the Blender exporter but I think this is a good intermediary step.

Thanks to ascloutier, this update is really what I want. I have tried this version just now. but I found the first problem still exist. I still got all of model when I select "ExportSelected".
(my maya version is 2016 - OS X 10.10.5)

And here are some other issue：

1. The export file contain all materials defined in maya, even if some of them have never been used;
2. The transparent attr export incorrectly (opacity always be 1 & transparent always be false).
   hope you can help ^^

Hey zhzh, thanks for the comments. I'm just putting together a fix for it still exporting all. I'm still a bit new to Maya and I didn't realize that the way the plugin was previously made would make export selected so difficult. This fix also takes care of all the materials bring in the file.

I'll look into transparency and opacity.

Also, I'm having a hard time testing exporting animation. I'm trying to make it so it should work with export all, but I don't think I'll be able to get it working with export selected. At least for now.
