iOS 9 Support

[threePhase]

Looks like a few things changed with iOS 9 & Xcode 7 which required some updates to the project. The following items are addressed with this pull request:

• Add explicit option to disable bitcode in order to maintain iOS 5 support
• Add support for arm64 devices
• Per iOS 9 requirement, added root view controller to dimming window
• In order to satisfy iOS 9 multitasking requirement, specify app requires full screen

I also went ahead and dropped the armv7 and armv7s architecture requirement in order to support arm64 devices. This also required rebuilding libwebp and libjpeg-turbo, so I went ahead and updated those from their respective master branches.

I realize the library updates might be a bit much for this request, so please let me know if you want me to break them (or anything else) out into a separate request.

Thanks for sending this in! For some reason I stopped receiving GitHub notifications for this repo so I wasn't aware of the activity in the past few months.

This is really 2 changes:

• Update the app for iOS 9
• Add support for arm64

The series of commits for iOS 9 seem reasonable. Regarding arm64 support however, I don't wanna do this. It's just too risky. The app was never tested on 64 bit and it's way too risky, and for no reward.

I'm happy to take the iOS 9 commits in if you update your PR 😄

PS: If you need to easily edit your PR branch, check out my app http://gitup.co/ designed for such things 😉

I have pulled out the commits which add support for arm64. Let me know if there are any other issues.

What's the deal with the _dimmingWindow.rootViewController change? Does the app crashes if built on latest SDK because of that? The one in the App Store certainly does not.

In any case, I feel this change should be restricted to iOS 9+ or 8+ or whenever that thing became a requirement. There are still some users of ComicFlow on old iOS versions and one must be very careful not to break them.

It seems that the latest version of the SDK requires that all windows have a root view controller. It seems that there was never a root view controller associated with the dimming window, so I was adding a new one.

If you would like I could wrap the change up in a runtime version check. Maybe something along the lines of this?

I just built ComicFlow with Xcode 7.2 and the latest SDKs both for simulator and device. The project builds fine as-is with no warnings outside of one about missing some launch storyboard. You must have changed something in the Xcode settings to make it iOS 9 only maybe.

Note that I just did a series of commits to make the app submittable to the App Store again: that required adding arm64 support, launch screens, etc...
