Save and reselect recently refreshed plugin

This allows developers to stay on the recently reloaded plugin
during and between editor sessions by making use of plugin
custom configuration file which is saved at project settings directory.

Also updated project settings to match with Godot 3.1-stable.
Also works with Godot 3.2-dev.

Disabled non-existing plugin which was used for testing apparently.
