[WIP] @orta => Updates to CocoaPods 0.36 Beta 1

In the process of writing that blog post, I thought it'd be prudent to update to the new CocoaPods beta. 

The project doesn't currently build – the compiler segfaults. It looks similar to the error we were getting in XCGLogger when optimizations turned on, so through some trial-and-error, I figured out that it was the `Pods` target itself. Disabling compiler optimization for this target fixed the segfaults – maybe something in cocoapods-keys? 

- [ ] Disable `Pods` optimizations using post-install hook
- [ ] Fix UIFonts pod (the resource files aren't being accessed properly, causing a runtime crash)

At any rate, I think including an example of how to disable optimizations on a specific pod would be :+1: in the blog post.
