Version 0.5

• Fixed a bug when swarming compose project files: these would be started up on
  the host and not within the cluster!
• Added possibility to pass project name or substitution instructions to YAML
  compose files being swarmed into the cluster.
• Fixed bug so that .env files pointed by project files that should be
  substituted will also be substituted and will be found by the project file
  when running compose.
• Fixed bug where compose projects would not be properly resolved when started
  using swarm.
• (Finally?) fixing login/pull bug so machinery will now be able to
  properly download from private repositories.
• Adding support for aliases, a new key called aliases under the VM
  dictionary in the YAML file. This should be a list of names that
  can also be used to point at the machine from the command line, but
  will also appear in the discovery mechanisms.
• Squeezed away a number of synchronisation bugs that would occur on
  slow hosts, we typically wait for good markers and retry a number of
  times sensitive operations.
• The default is now to use the locally cached images when
  initialising virtual machines. This will speed up initialisation in
  a number of cases. Furthermore, this allows to push private images
  on the machines withouth having to transfer repository credentials
  or similar.
• Factored away UNIX/linux specific commands into a separate package
  to keep down the size of the main code-base.
