selenium testing

[John Wiseman]

I've started creating a selenium webdriver testing script, selenium_test.py.

To use it, first do sudo pip install selenium and make sure you have firefox installed.  Then start a software-in-the-loop simuation and start mavelous.  Arm the vehicle.  Now you can run the script and it will run a couple tests in Firefox:

[jwiseman@ubuntu mavelous (master)]$ python selenium_test.py -v

Ensure that the simulated uav is ARMED.

test_flight_mode_buttons (__main__.MavelousWebTest)

Testing flight mode buttons ... ok

test_gps_button (__main__.MavelousWebTest)

Testing GPS button ... ok

It's already helped make one issue with the navbar buttons clearer (https://github.com/wiseman/mavelous/issues/38).
