Fixed issue where saving a new Scene Load Action for Keybindings incorrectly saved it with the path of the default scene instead of the path of the file that you had selected. This could result in multiple actions being created for the same scene file - you can tell if that's the case when selecting an option in the dropdown highlights multiple options. If you notice this, simply delete the duplicates using the delete button.
Prevent initializing another copy of the plugin if it's already present in session plugins
