Sia v0.4.4

This release focuses on improving the reliability of uploads. Previously, it was possible for uploads to "stall out" and never reach 100% redundancy. As of v0.4.4, uploads will always complete (provided there are enough hosts, and coins to pay for the upload). To complement this improved reliability, Sia-UI has a new "Add Folder" feature that allows you to easily upload a whole directory of files.

One of our big goals for the next release is to actively monitor the health of files, and repair them as needed. This means reuploading pieces when their contracts are close to expiring, and moving pieces to new hosts if their current host is unresponsive.

Thanks to @mtlynch for his contributions to this release. After some lengthy discussion, he convinced us of the benefits of mocking and explicit dependencies, which we now intend to use across the Sia codebase.
