Implemented IPC message to check whether cookies are enabled.

If you want to test this simply load some page in the browser. Go to
settings and disable cookies. Then type in the address bar :
	javascript:alert(navigator.cookieEnabled);
You should see a box saying "false" if you see true or even worse
don't see anything at all the test has failed.

BUG=63309
TEST=Disable cookies and try alert(navigator.cookieEnabled); should be false.
