Pencil: [Suggestion] Show unsaved sign on the program title

[puetsua]

I think it would be nice to have a star sign after filename if the file haven't saved. e.g.
C:/user/mybox/myartwork.pclx* - Pencil2D

@hankofficer I like this idea, similar to Blender and other software, although maybe we should be even bolder about it and display a message haha, thee are a lot of kids using this software and they have short attention span :stuck_out_tongue_closed_eyes:

I'm working on it :D
