Order items in XCode project navigator by name (TextureGroup#835)

* Order items in XCode project navigator by name

It is a bit hard to find file in folders with long list of file, for example Tests. Sorting items by name makes this a bit easier and brings order.
If there are child folders, they are ordered before files. Keeping folders sorted by name may be reasonable alternative as well.

* Re-sort after merge.

ASNetworkImageLoadInfo.h is still here, not sure why showing removed in this commit. Had this file duplicated  reference previously?
