Run Chrome incognito in split mode

Since we now have a LRU cache, be very paranoid about the
incognito <-> normal browsing boundary. This runs the extension
in a separate process in incognito mode (no shared cache, etc.)

Fix host-only cookie duplication & leak

Currently we create duplicate cookies (!) for host-only cookies, one
secure, one insecure. This is because we're always setting the domain
parameter, regardless of the hostOnly value.

See: http://developer.chrome.com/extensions/cookies.html#method-set

Closes issue #159

Chrome: Streamline redirect counter

(For issue #12)

This refactors & optimizes the old redirect counter.

The redirect counter exits to catch infinite HTTPS <-> HTTP loops. The old counter
was messy, constantly churning a small array of requestIds. I think it was written
before the new API call: onBeforeRedirect.

(The old counter also generated a lot of orphan entries, e.g. when another
extension or the browser itself aborted requests / redirected to about:blank.)
