Ditching the legacy flipper.

I was quite proud of it, but no-one seemed to use or like it. With Opera
now supporting columns, and the recommendation for IE being to use
ChromeFrame, the legacy flipper is really just bloat.
Removing support for iOS < 4.2.

This gets rid of the TouchMonitor workaround, of which I'm very proud,
but which is unquestionably bloat. iOS 4.2 is the last version to
support the iPhone 3G, which is definitely an intended target. It's too
difficult to support the original iPhone and 1st/2nd-gen iPod Touches
going forward — use the last version of the Monocle 2.0 series if you
want to support iOS 3.1 -> 5.0.
Removing retired (iOS < 4.2) tests in Env.
CSS2 multi-column layout support is now required.
Added place#pagesInComponent.

This makes it easier to display a page number control like "Page 13 of
73" or "60 pages left in this chapter."
Restoring brokenIframeTouchModel test to disqualify old iOS.

Update browser detection for Nook/Sony Reader UA quirks.

Also adds some standard tests for offline caching and storage support,
because that stuff can be a bit weird in older WebKits, and it's a
pretty common test for Monocle applications.
