Switched forums insertion/removal to Fade instead of Automatic, which looks a bit less sloppy when making a lot of changes at once
Fixed bookkeeping issues in forums list, moved collapsed/uncollapsed status into settings instead of restorationState
Update Crashlytics.
Document undocumented settings keys.
Rewrite forum tree as a UITableViewDataSource.

A la the fetched results controller data source. This one provides for the
favorites section with a -topDataSource property, freeing the forums list
controller to deal exclusively with the favorites section. Moreover, it's
simpler, which should reduce crashes and bugs and the subsequent inability to
fix them.

Other opportune changes:

* AwfulForumsListController no longer implements
  -{de,en}codeRestorableStateWithCoder: as there is no longer anything to do.
* AwfulForumsListController stops observing the reachability changed
  notification, preventing possible multiple or spurious refresh attempts.
* DRY up a bit of AwfulForumsListController.
Centralize forum expanded settings in AwfulForumTreeDataSource.

Keeping AwfulSettings out of the model classes feels like a good idea. As a
bonus, this fixes scraping tests.
Finish renaming Parsing folder to Scraping.

Forgot to change the folder on disk!
Delete AwfulPost.attachmentID and AwfulPost.editDate.

They're not used by anything, we just dump the HTML of the post.
Move AwfulUser -idiotKing property to new model version.

So beta 2 users don't lose their cached data.
Delete unused font_size setting from Settings.plist.

(Though I imagine it'll soon make a return.)
Move AwfulPostViewModel to Posts folder.
Tidy up AwfulLoadingView.

* Delete unused AwfulLoadingViewType enum.
* -retheme defaults to no-op.
* "Loading" label defaults to Dynamic Type font.
* Adopt newer coding style.
Tidy up UINavigationItem+TwoLineTitle.

* Delete redundant property declaration.
* Document -titleLabel property.
Fix logging in and sending to Instapaper.

* AFNetworking's default response serializer doesn't accept text/plain (go
  figure).
* Gotta resume the NSURLSessionDataTask when you make it this way.
Theme Instapaper log in view controller.

As a bonus, tidy up some of the code.
