Expanding Brozzler's logging in capabilities

Browse Source 
Some sites don't allow you to login without clicking on a button to open a retracted modal.

This update to the login code allows Brozzler to click on all elements that we think are related to opening a login modal.

Then, if there isn't a regular form, we will attempt to fill out abnormal form schemes.

The test_try_login test has been expanded for the new type of login form we are supporting.
