Bug 522181: [Webkit2] Implement clearSessions() on WebKit2.

The WebKit2 implementation of clearSessions() will remove session and
non-session (those with an expiry) cookies. The API specifies only the
former shall be removed but there is no way to be more selective for
now.

Tested on WEBKIT1 and WEBKIT2 using the JUnit test provided. The general
test approach involves manipulating cookies through javascript.

Some additional tests have also been added. test_evaluate_Cookie acts as
a sanity check for the correct functioning of 'document.cookie' and the
browser.evaluate() functionality. test_get_set_Cookies will eventually
help with further implementation of the Cookie API on WEBKIT2.
