created podspec

Hi I created this pod spec for your project, We use your framework and my company uses Cocoapods for a while now and we get projects that we use your library with, So I have forked your project so I can use it with Cocoapods internally , But I know alot of people now use cocoapods and alot a new iOS developers and you will get more poeple using your service as alot of people might not know about filepicker and having a pod will have your product listed on cocoa-control's which will let alot more people know about you product if you do use this you need to replace the author name and email address which I just put place holder in.
Rename Filepicker.io.spec to FPPPicker.spec
Update FPPPicker.spec
