Update module-info.java

[HelgeStenstrom]

All exports are removed from the module-info.java file, because it's not likely that this app needs to export anything. Two opens statements are added, to try to fix behavior which otherwise changes. The programs seems to work in my limited test, but the behavior needs to be checked by someone else.

Have you runned the application after you modified the module-info.java :)?

[HelgeStenstrom]

Yes, but probably not enough. I don’t know what functionality to exercise.

One of the “opens” statements that I added was because icons in the playlist weren’t visible. I was lucky to see it. The player ran fine without the icons.

Merging :)
