Change the SDK to Xcode default - allows compilation with Xcode 4.6.
Copy the headers when building the library so that they can be used in superprojects including this project as a submodule.
Add new "FCEasingAnimation.h" header that includes other headers, to allow "#import <FCEasingAnimation/FCEasingAnimation.h>" to work when using the library in other projects.
Add .gitignore file to stop Git noticing private, local Xcode files and warning me that I have uncommitted content all the time.
Merge pull request #2 from th-in-gs/master

Changes to allow easier inclusion in other projects.
