v4.0.0-alpha.4

This new release includes some fixes and clean ups to the code, but the major announcement is: the Logos Linux Installer program can now update itself, meaning that once you download it from GitHub once, you shouldn't need to go to GitHub again.

While there are other features and enhancements we want to add going forward, this is the last major feature we had planned before beta, and thus we are on to testing before a beta release. We still have some other features we want to release, such as #85 which will allow us to resume an interrupted install. At this point, most of the other feature work we have planned is adding additional distro support.

EDIT: The binary in this release has been edited in order to apply a hotfix for a couple of errors found since release. This binary reflects a build up to this commit: cc10a4e
