Siacoin Release wallet v1. 3.4

This is a patch release that focuses on stability and correctness improvements to the renter. In addition to a bunch of minor improvements, contract spending is now reported more accurately, and individual contracts can be canceled without canceling the whole allowance.

Thanks as always to everyone who contributed to this release, and everyone who tested our release candidates!

As a reminder, the Sia project has moved to GitLab, but we will continue to make GitHub releases for backwards compatibility with siac update.
