Hasher beta v1

About 10 users currently use Hasher on a regular basis and that's amazing! Thanks to them really.
Because of this, and because no other issue has been reported, I'm releasing the beta version of Hasher. It's been running perfectly for weeks now, so I think it's ready.

This release also comes with a few more features! Most importantly in my opinion is the smoothing parameter that allows a more robust and effective profit switching mining. The two others are just some more tweaking options: how frequently you want to check for profit, and what estimate you want to use.

Finally, there are some minor bug fixes, better logging etc. Thanks again for using Hasher!
