v0.2.0

This release has multiple backwards incompatible changes against the previous release.

Changes:

• Using extras to install Docker and Vagrant dependencies

  • pip install arca[docker] or pip install arca[vagrant] has to be used

• Automatically using cloned repositories as reference for newly cloned branches

• Using Debian as the default base image in the Docker backend:

  • apk_dependencies changed to apt_dependencies, now installing using apt-get

• Vagrant backend only creates one VM, instead of multiple -- see its documentation

• Added timeout to tasks, 5 seconds by default. Can be set using the argument timeout for Task.

• Added timeout to installing requirements, 300 seconds by default. Can be set using the requirements_timeout configuration option for backends.
