Broken example projects

There are several issues with building the example projects.
The results below are from https://github.com/tong/armory_examples_browser/actions building for the html5 target
It uses my [fork of armory_examples](https://github.com/tong/armory_examples/tree/examples-browser-compat) where every project is flattened to repo root, but beside that unchanged.

Also this doesn't mean that the projects run correctly, these are just the build time errors.

Most logic nodes examples fail to upgrade the blend files to the actual armory version, for example:
```
blender -b armory_examples/logic_event_object/logic_event_object.blend --python blender/build_project.py

Start by rerunning the Blender command shown for logic_event_object and review examples.log alongside the generated node_update_failure report. Trace the upgrade path through blender/build_project.py, armsdk/armory/blender/arm/logicnode/replacement.py, and armsdk/armory/blender/arm/props.py; done means the listed failing example projects build for the html5 target without the reported errors.
