Improvements

Scripting with vg is now much better supported. vg should now keep working even when you have run set -eux before.
Starting with this release binaries for some architectures are precompiled, in case you want to pin a specific version of vg for your CI.
A test suite with coverage is now run on Travis. This should give more confidence that changes don't break vg.
Some error messages have been improved with much more detailed steps that should be tried to fix the issue.
