We should be able to override some settings from command line.
For e.g. we should be able to select the webdrivers from command line:
play webdrive:test --drivers ie,firefox
We should also be able to select what tests to run:
play webdrive:test --skip test1,test2 - Runs everything except test1 and test2
play webdrive:test --only test1,test2 - Runs only test1 and test2
