Call -[UIWebView stopLoading] before its delegate deallocates.

Apparently this might help prevent some crashes from the WebThread.

Bonus: move -[AwfulBrowserViewController viewDidLoad] and
-[AwfulPostsView dealloc] to more helpful places.
Stop removing nonexistent shadow from UIWebView.

Left over from old iOS versions.
Nil out table view data source on dealloc.

Seeing some crashes that look like a table view calling a deallocated data
source. Maybe this will help.
Make and use script to fix copyrights atop files.
Fix shortcut keys overstepping the input accessory view on iPhone.
Fix Jump to Page sheet colors and dismissal on iPad.

* Wasn't being dismissed on iPad.
* Buttons used the tint color for text, which looked dreadful.
Don't try to delete in-memory data stores.

Because we'll fail every time.
Fix compile warnings in tests.
Fix test checking wrong post's HTML.
BYOB & FYAD Action Sheet colors
Update contributor list.
Extract AwfulHTTPRequestOperationManager and its default configuration.
AwfulForumsClient is the new AwfulHTTPClient.

When we subclass framework classes for relatively trivial customization, we're
tending towards simply replacing the existing prefix with "Awful" (e.g.
AwfulNavigationController, AwfulAlertView). So one expects "AwfulHTTPClient" to
be a customized subclass of AFHTTPClient. It's not.

I also removed excessive dot notation (`[AwfulHTTPClient.client blahblahblah]`)
because Xcode's refactoring doesn't pick it up. Nor does its autocompletion.
Also it's kinda ugly?
Import into Core Data through a background managed object context.

Get that stuff off the main thread!
Update HTMLReader to 0.5.1.

Delete pointless link from README.
Update HTMLReader to 0.5.2.
Fix left/right arrow in popovers.
Fix locating post with never-encountered thread.

Forgot to save the newly-created AwfulThread, so the post never got its thread
set. This led to an eventual crash fetching the page from a thread with a nil
threadID.
