Addresses [Issue #761](http://code.google.com/p/phantomjs/issues/detail?id=761).
This is a squash of 5 commits.
1. Complete reimplementation of the CookieJar and the Cookie API - Part 1.
The save/load mechanism is inspired by the Qt Demo "browser".
More info: http://doc.qt.nokia.com/4.7-snapshot/demos-browser.html
2. Making the CookieJar a singleton.
We need to have multiple NetworkAccessManager to monitor the network activity of the page,
but we also need to maintain 1 CookieJar: in this way we now have a shared bucket of Cookies.
3. Exposing the new Cookies API to the JS space.
* Updated the completions.
* Ensured backward compatibility of the API.
* It's now possible to "phantom.cookieEnabled = false" to disable cookies completely.
* New methods: addCookie, deleteCookie, clearCookies
4. Provided some internal Doc for the new Cookies API
5. Ensuring the "page.deleteCookie(name)" method works only if a cookie name is given.
