Integrate Sparkle framework for updating.

[alloy]

• Integrate Sparkle framework.
• Create rake task that updates the versions feed when the release task is used.
• Create feed containing the versions in this repo’s GitHub Pages.

Will this support the smallest compressed archive format that @kylef mentioned?

This has a dependency on CocoaPods/CocoaPods#2801 because Sparkle framework needs to be code-signed.

CodeSign /Users/kylef/Library/Developer/Xcode/DerivedData/CocoaPods-gkbnzzpayswnqugwpdghvwpgzfew/Build/Products/Debug/CocoaPods.app
    cd /Users/kylef/Projects/CocoaPods/Rainforest/CocoaPods.app/app
    export CODESIGN_ALLOCATE=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate

Signing Identity:     "Mac Developer: Kyle Fuller (...)"

    /usr/bin/codesign --force --sign ... /Users/kylef/Library/Developer/Xcode/DerivedData/CocoaPods-gkbnzzpayswnqugwpdghvwpgzfew/Build/Products/Debug/CocoaPods.app

/Users/kylef/Library/Developer/Xcode/DerivedData/CocoaPods-gkbnzzpayswnqugwpdghvwpgzfew/Build/Products/Debug/CocoaPods.app: code object is not signed at all

Regardless, the sparkle branch has most of it done.

[alloy]

I think that for now we can just solve the code signing in the Xcode project, so I’d rather merge this into master sooner than later.

[alloy]

This branch does not yet do any of the required Sparkle configuration, right? Or am I overlooking it in the huge number of files? :)

[kylef]

@alloy the only configuration is the feed URL from what I understand. We don't have one yet 😉.

[alloy]

I think we should just host that feed in this repo (the GH Pages feature) so we can keep it all localised and easy to do from the release task.

Will you look into creating the feed or should I?
