Introduce camera access for ios and a example.

Depends upon Photolibrary on iOS kivy/kivy-ios#154

What is the holdup for this merge? It would appear to add a significant capability to kivy-ios

@gorgonaut04, it was not tested yet. Would you mind checking out the camera_gallery_ios branch and reporting back?

[gorgonaut04]

I intend to, but I need to drive 2 hours to use an imac, and won't be able to for about 2 weeks. The availability of this feature is really the catalyst for getting started on an iOS version of our android app ( barlyapp.com ). We really aren't iOS people at all, so we're hoping that Kivy would make the jump easier

If others do not jump in for testing, we would be glad to get feedback on it two weeks from now. ;)

Any news on this?

[gorgonaut04]

I finally got a chance to focus on getting iOS going and I can confirm that the camera works great!! This was actually one of the easier features to port over. Thanks @akshayaurora!
