Editing the download path setting doesn't update already-downloaded packs

[NoiTheCat]

I'm reorganizing my folder structures and wished to move where I'm saving the songs that this downloads into a slightly different path than before. After changing the setting and clicking Update, it proceeds to redownload everything from the pack into the previous area, re-creating any non-existent folders in the process.

I would suggest to prevent this from happening:

• Allow the individual pack's path to be moved, or
• Show a message when editing the download path setting to state that any existing packs will stay where they are

Thank you very much, this has been super useful to me!
