Andrii Doroshenko (Xrayez) 871b1d76d2 Accept global classes for MainLoop type in project settings
`application/run/main_loop_type` setting can handle custom global
classes (`class_name`).  For instance: `MySceneTree`.

The setting's default is changed from empty to `SceneTree` as to give
some hint of what kind of input is accepted for the main loop type.
