2.3 branch

[navisingh]

The only change required to support swift 2.3 is
let alpha = CGImageGetAlphaInfo(CGImage!)
instead of
let alpha = CGImageGetAlphaInfo(CGImage)
in the file UIImage+Cache.swift

Hey @navisingh, I've created a branch and asked the author of #52 to point it to that branch instead.
This is the PR in question - #52

@navisingh #52 was just merged so if you point it to use swift-2.3 you should be fine 😎

@zenangst would you mind releasing swift-2.3 branch? I want to use Cache in my private pod, but it's not possible to specify a branch in podspec's dependency.

@zenangst I've noticed a 2.0 release with Swift 3.0 support. Is it possible to make a maintenance release of 1.x for Swift 2.3?
