v0.1.5: small fixes + docker packaging fix
This release mostly honestly includes integration tests, which did catch quite a few bugs, the fixes for are contained within.
- Restrictions on named hosts (from the central member's "name" field) are less restrictive and also diagnostics should be easier to understand now.
- Comment and whitespace handling in hosts files is much more sane.
- In some situations the zeronsd instance would fail to properly evaluate the network from zerotier-one, failing to start the daemon. This has been resolved.
- Additionally, docker packaging has been resolved and is now future-proofed with package testing.
