GUI Fixes, editor scaling support

- Fixed RTNodeEditor example having no root rect and thus context menus not appearing
- Fixed broken GUI when using 2019.3+ Editor Scaling feature
- Fixed spelling mistake ForceGUIDawOffScreen -> ForceGUIDrawOffScreen in Node.cs
- Changed toolbar information, made it more compact
- Moved standard NodeEditorFramework.Standard.NodeEditorInterface to the Standard folder where it belongs
