Rename Source/Pocket folder.
Fix post action sheet never appearing on iPhone.
Stop crashing on iPhone when long-tapping threads.
Fix font size stepper layout in thread settings sheet.
Send to Instapaper.
Pick a nit.
Awful Browser can rotate to landscape on iOS 5.
Brighter action icons.

@ridilla pointed out the color burn fill mode for the gradient. Some tweaking
later, it looks much nicer!
Fix Instapaper login sheet enter key and report invalid username/password error.
Add format attribute for compile-time checking.
Widen jump-to-page picker.
Highlight quotes that don't link back to the post.
Greatly improve accessibility of new action sheets.

VoiceOver will no longer read out the content behind the sheet. The cursor is
moved to the sheet when it's presented. And the buttons on the sheet are
properly sized and marked as buttons.
Set infinite scroll enabled in bookmarks after fetching each page.

Infinite scroll is now disabled after fetching the last page of bookmarks even if there's more than one page.

This also fixes a problem where deleting a bookmark would incorrectly disable
infinite scroll. It's not perfect -- deleting a bookmark then loading the next
page will "lose" a bookmark until a reload - -but it's closer.
Update Crashlytics framework.
Fix awful:// URLs tapped in e.g. Awful Beta opening in Awful.

If multiple installed apps register the same URL schemes, it's nondeterministic
which one gets called by iOS. So let's skip iOS's routing for internal awful:
URLs.

The problem persists for other apps that open awful: URLs, but we can't really
fix that.
Hide sidebar when opening a thread from an awful: URL.
Hide separators after the last cell in thread lists.
Tweak "show sidebar" gesture on iPad.

A pan gesture recognizer has much nicer interaction with scrollviews' gesture
recognizers. And it easily allows for a "peek" gesture: swipe right to reveal
the sidebar but don't let go; check the threads, then swipe back left to hide
the sidebar once more.

In the meantime, the recognizers are named after what they do, and the two that
hide the sidebar now share an action method.
Version bump.
