Update the add-on for Blender 2.90

[jtiai]

Blender version:
2.90

Issue description:
Current plugin doesn't support Blender 2.90 which was released on 31st of August 2020.

Blender 2.90 is also the default version blender.org offers now.

What specifically doesn't work with 2.90? I've been using it with blender 2.90 for a week or two now and haven't noticed any issues.

It does not even show the menu entry for exporting at all.

Can you describe the steps you went through to install it? Also what branch/commit are you using for blender and the exporter?
I can confirm after work, but I believe I'm using the master branch of the plugin with the Arch package for blender 2.90.1, and everything seems functional so far.

I copied everything from here into ~/.config/blender/2.90/scripts/addons and afterwards I installed the zip over the addon menu in blender and activated the addon. I am using the download from blender.org. I am on arch, too but I have some very strange issues using the blenderpackage. Same with godot. Using the arch godot package: Importing an dae or gtlf and showing it: looks fine. Save that nodetree, hang it under another nodetree, only the boundaries show up! Nothing to see from the model. Same with cameras and lights, nothing else is drawn. But when using the file from the zip from godotengine.org, everything works fine. But only when repeating the steps. When using the file saved from the godot I installed with pacman the error is also in this one.

I don't know what is wrong with those archlinux packages.

Just to clarify, you should copy the io_scene_godot subdirectory to ~/.config/blender/2.90/scripts/addons/io_scene_godot, not the entire repo.

If you have specific bugs with 2.90, they'll be easier to fix if you file separate issues with repro steps and a minimal example file. Cheers!
