Support for Blender 3.6 LTS

Blender 3.6 LTS was released yesterday; luckily this time there were almost no breaking changes, so this PR is quite small:

• Changed version numbers
• Added support for the new Mix node that replaces the Mix RGB node (closes Blender 3.4 Mix Color Node support #2821).

In the 3.6 project, I also added some optional tasks that need some more research (the Blender release notes are rather sparse in those cases), but these aren't important at the moment.

Unfortunately, Blender now initializes the name of new custom node trees to the bl_label of the node tree/node editor (Blender commit). In our case this calls new node trees Logic Node Editor, which is not only semantically wrong but also conflicts with Haxe naming and thus raises a warning a la

WARNING: The logic node tree "Logic Node Editor" had to be temporarily renamed to "LogicNodeEditor" on export due to Haxe limitations. Referencing the corresponding trait by its logic node tree name may not work as expected.

It might be possible to listen for tree creation events and then quickly rename them, I will try to find a workaround in the next days but it could be impossible...
