Started refactoring to get the test suite running with karma test runner. So far, the ware suite can run. (Might have broken everything else in the process though)
Karma-ify city test suite
Convert the player test suite
Add karma configuration and file for importing test suites to be run.
Update instructions regarding running the test suite
Get the main game running again properly
Add a second city
As long as this is going to run in a browser, it seems a bit odd to run the test suit on node. Therefore replaced the test runner with karma, which can run it in a set of browsers, actually matching the environment it will be run in.
