[PROBLEM] Update library

[TheOldPresbyope]

...
MPD is scanning only the OSDISK folder but thumb-gen is scanning everything. 
...

That's the whole problem. Why scan everything if we specified a selected folder?

No, that's not the whole problem for the rest of us, so it's not high on the priority list.

In the meantime, you're free to work up modifications to the appropriate routines in moOde, demonstrate they work, and submit a pull request to the repo, just like the rest of us are.

I'm done here.

Kent
