Added tests for adding lists when the Wunderlist window is minimized, closed, or in Compact mode. Fixed some window-related issues exposed by task and list tests.
Added local copy of headerdoc as a dependency for `make docs` to allow others to more easily generate documentation. Updated script syntax to appease headerdoc's poor support for AppleScript.
When searching, Wunderlist does not focus the newly added list for naming. Added a test to cover this case.
