- Fix tests running on ``Google Chrome``. (Issue 20)

- Google Chrome: Add temporary download directory support. It is
accessible as a ``pathlib.Path`` via ``self.layer['selenium_download_dir']``.

- Google Chrome: Add support for head mode.

- Add beta support for ``Microsoft Edge``. (It currently supports all features
besides headless mode and download directory support but is only tested using
the tests of ``gocept.selenium``. **Caution:** Edge does not seem to be
really stable on Mac OS, after some test runs it sometimes refuses to start
and requires to delete its preferences etc.)

the layer.
