Crash when using cells defined in storyboard

[fgeistert]

When using Cells that were defined in storyboard (not in .xib or programmatically) the DataSource crashes.

We think it has to do with the DataSource trying to register the cell, even though that was already done by the storyboard.

It is likely caused by a change introduced in #24.

Fix until this is resolved properly: set registerNibs to false. You will then also need to register als xibs manually.

Fixed in https://github.com/allaboutapps/DataSource/releases/tag/8.0.2 and reverted the auto-registration of call cells. Only xibs and the SeparatorLineCell are registered automatically.
