Added instructions for OS X to the README.

Changed the info included in the did-save-merge-changes delegate and notification methods to use the NSManagedObjects from the save, rather than the object ids. This recent change to object ids broke conformance on iOS 6.
Remove reference to duplicate header files

The :submodules attribute causes the Dropbox SDK to be downloaded and the source_files references the header files. Meanwhile, the cocoapods dependency already downloads and includes the same header files (in a different location). The result is a duplicate symbol error.

Remove reference to duplicate header files
Optimization in which only entities that have changes are included in the integration loops for any one store mod event.
(Change inspired by Kevin Ross.)

Added news blog and twitter account to online resources.
Changed the methods that determine whether rebasing is necessary to be asynchronous. They can take a while, because they perform fetches, and they were blocking the main thread.
Fixed bug in Idiomatic for iOS. It was failing to leech for Dropbox when the Dropbox app was used to authenticate. The reason was that when using the app, the main app goes to the background, and when it reactivates, it attempts a new sync. This triggers a second leech. Normally that wouldn’t be so bad, because the second leech just issues an error and stops, but Idiomatic was using a leech error as a reason to cancel syncing.
This has been fixed by only terminating sync if there is a leech error, and the ensemble isLeeched property is false.
Changes to add support for Mac OS X 10.7
A few more fixes to make the framework compatible with Mac OS X 10.7.
Added more safeguards when triggering iCloud downloads. If a download has already been initiated for a given URL, it won’t be initiated again until the download has completed.
Fixed some bugs in rebasing that could cause a device to not import objects in particular circumstances. The test for whether a full integration is needed is much more robust, ensuring stores replay all changes if they have been ‘abandoned’. The test of abandonment is simply whether a merge event exists that is newer than the baseline. This will cause a few more full integrations, but is preferable to being out-of-sync.
Several new rebasing tests have been added, which were failing before the changes.
Added a test for a non-nil object id before trying to fetch the object. Generally never nil, but could be triggered if the DB is removed.
Added a few extra  nil checks in CDEEventBuilder. Some reports of crashes due to nil.
