added existingCount to set cookie reporting object, gave up on canAccess, fixed where we were not collecting the host during cookie-add and cookie-changed
a tweak to make the existingCount property actually work - needed a string not a nsIURI
removed success arg from parseAndLogCookies and removed success value from usage of parseAndLogCookies
