Fix for [#31396] "bge.logic.LibLoad fails to import text blocks" reported by Leonard Ritter.

Blender's import function check's the Text datablocks in main for additional modules for importing. However, libloaded scenes were 1) not loading Text datablocks and 2) not letting bpy know about them. Text datablocks are now loaded if a Scene is loaded and bpy can now looking through extra Mains to find additional modules.
