Subject: [PATCH] Use Docker for easier test running (#86)

Switches to CircleCI instead of Travis, which handles running tests in
Docker much better, especially since Travis is really slow (~30min vs
2.5min on CircleCI).

The Docker image is based on
https://github.com/tweekmonster/vim-testbed, and targets are added to
the Makefile to build/push it.

 - Run the tests with the command::
 
    $ rspec spec
+- Alternatively you can use Docker::
+
+   $ make test_docker

+- You can select tests based on line numbers, e.g.::
+
