`lzip` is used for its great compression (better even than `xz`) and
properties that make it a viable format for long-term archiving (feature
that `xz` is missing).

Also add some docs regarding release process.
Re: #3912, #4045
- Add /usr/local to the search paths for includes and libs.
- Build toxcore before updating homebrew. Updating homebrew somehow breaks the
toxcore build.
The auto-updater is essentially done, except for the GUI. For now this is only an API.
The API works, but the tools to manage the update server would need some love
