Dev:OBWelcomeController

OBWelcomeController is a view controller subclass in OnBoardingKit.framework.

A few notes
- contentLayout:2 seems to be the only way to go. Other options appear to crash.

- You can use any regular UIImage. The system image is used here as an example.

- Outside of contentLayout, all arguments for initializing (and for adding an item - explained in the next section) can be nil. If an argument is nil, its corresponding view is not created, and OBWelcomeController adapts the spacing accordingly.

This also removes the blur effect from the button tray.
