fix(web-server): close webserver after running

When we're done running the tests and all clients are disconnected,
we should stop the http server. This way another karma instance (or
anything else for that matter) may reuse the port later.
fix(runner): Karma hangs when file paths have \u in them #924

Escape backslashes in paths, which happen in Windows,
to prevent bad IDs (e.g. aaa\uuuu).
Add unit test with path with backslashes.

refactor: remove useless log
docs: updates for 0.12 release

The readme got pretty out-dated, it's gonna be easier to maintain just one thing...
feat(init): generate test-main.(js/coffee) for RequireJS projects
docs(requirejs): normalize paths to RequireJS modules
fix(web-server): detach listeners after running

Remove listeners from the global process and the webserver when we're
done. The EmitterWrapper can be used to wrap any EventEmitter and
remembers the listeners that were via the wrappers addListener/on
function. Then the wrapper's removeAllListeners function can be used
to remove the wrapper's listeners, leaving the listeners that were
added directly to the unwrapped emitter attached.
