Declarations added to collectionview layout header.

Clean compile for NSCollectionViewLayout abstract class

Add header for NSCollectionViewFlowLayout.h

Add skeleton implementation of NSCollectionViewFlowLayout

Add implementation for simple setter/getter methods.

Correct compilation error with non-clang compilers

Fix compilation issues

Add getter/setter for collectionViewLayout

Skeleton of NSCollectionViewTransitionLayout implementation

Add encoding/decoding for collectionViewLayout key

Make NSCollectionViewGridLayout default if the NSCollectionViewLayoutKey is not set

Add protocols for DataSource and Prefetching for NSCollectionView

Add 10.11 methods to delegate declaration

remove templating from NSCollectionViewDelegate that gcc can't handle.

New delegate methods for NSCollectionViewDelegate to support NSSets of NSIndexPaths and multiple selection.

Reset .travis.yml to the proper version and modify NSCollectionView.h to use forward declarations for both NSPasteboard and NSPasteboardWriting so that we don't explicitly import.
