The folder already knew how to stop properly, but the fs.Walk() didn't and can potentially take a very long time. This adds context support to Walk and the underlying scanning stuff, and passes in an appropriate context from above. The stop channel in model.folder is replaced with a context for this purpose. To test I added an infiniteFS that represents a large amount of data (not actually infinite, but close) and verify that walking it is properly stopped. For that to be implemented smoothly I moved out the Walk function to it's own type, as typically the implementer of a new filesystem type might not need or want to reimplement Walk. It's somewhat tricky to test that this actually works properly on the actual sendReceiveFolder and so on, as those are started from inside the model and the filesystem isn't easily pluggable etc. Instead I've tested that part manually by adding a huge folder and verifying that pause, resume and reconfig do the right things by looking at debug output.
