Summary:
In the Feed view, all the -isEqualToDiffable: implementation only checks the pk, a.k.a the identifier.
Let's mimic that behavior.

Summary:
We have seen unnecessary flashiness updates for any section reload updates.
Basically we have 1 section for 1 cell, which is recommended by the IGListKit document in https://instagram.github.io/IGListKit/best-practices-and-faq.html, specifically:
> "We highly recommend using single-item sections when possible."
However, the issue is that whenever we update the underlying data model, we would trigger a delete+insert for the section reload.
In order to mitigate that, we can fix this delete+insert changes or we use the `IGListBindingSectionController`, however, the latter one requires more refactoring plus view model wrapper to have `isEqualToDifferable:` to return YES, which seems less than ideal.
I am proposing that we add an option to the `IGListAdapterUpdater`, as `preferItemReloadsForSectionReloads` so that when it's set to YES, we would trigger the proper `-[UICollectionView reloadItemsAtIndexPaths:]` which handles the cell update properly.
This option also handles the case where the number of items in the section is changed before and after the updates, in that case, it will fallback to do the "delete+insert" section operation.

- Run setup script with CP 1.5.3
- Update to Xcode9.4 recommended settings
- Fix Xcode warnings about NSUInteger
This way we can avoid these changes on other open PRs/diffs.

Summary:
Changing the API to avoid overiding `-[NSObject isEqual:]` because of the side effects it brings (e.g. `-hash`). Not to mention the problems with Swift 2.3.
Fixes#65.
