Upgrade gut to v9.3.0

Fix a ton of gut errors:

Checked out gut tag v9.3.0 and replaced our addons/gut/ folder with
their addons/gut/ folder. When running, gut tells us it's copying our
config to use as a template, but I don't think we want to delete the
template because all repo devs should use it:

|| GUT Info:  Copying [res://.gut_editor_config.json] to [user://gut_temp_directory/gut_editor_config.json]
|| GUT Warning:  File [res://.gut_editor_config.json] has been moved to [user://gut_temp_directory/gut_editor_config.json].
||     You can delete res://.gut_editor_config.json

|| GUT Warning:  File [res://.gut_editor_shortcuts.cfg] has been moved to [user://gut_temp_directory/gut_editor_shortcuts.cfg].
||     You can delete res://.gut_editor_shortcuts.cfg
|| GUT got some new images that are not imported yet.  Please restart Godot.

The Gut editor panel seems to work and I can run tests (they don't all
pass).
