Automate running browserbench.org benchmarks

The following command line flags are supported for all benchmarks:

• -b': The browser to run the benchmark in. The valid options currently are 'chrome', 'safari', and 'stp'.

• -e: Path to the executable for the driver binary.

• -a: Additional command-line arguments to use when launching the browser. Currently supported only for Chrome (i.e. with -b chrome).

• -g: An optional githash associated with this run. This githash is reproduced verbatim with the result, and is not used for any other purpose.

• -o: Path to the output json file.

• --chrome-path: Path to the chrome binary. If not present, default binary is used.

In order to use these scripts, you must have the following present:

• Install [chromedriver][https://chromedriver.chromium.org/downloads].
• Install [selenium][https://pypi.org/project/selenium/].

Safari requires enabling remote automation:

1. Enable the developer menu in the Advanced tab of Preferences.
2. Enable 'Remote Automation' via the 'Developer' menu.
3. Run safaridriver --enable.
