[README.md] Fix CocoaPods typo
Share scheme

Carthage requires schemes to be shared so that it can find them.
Update README with installation instructions

Adds instructions for installation with Carthage, and notes that
CocoaPods support is coming soon.
Add OS X target

Rearranged the project a little bit and added an OS X target so that
this can be used for mac apps.
Run Liftoff on project

This updates the project settings with our recommended defaults.

Notable exception is that we're setting the indentation to 2 spaces
instead of 4.
Add tests to scheme test actions

This allows us to run the tests under the scheme with the `command + U`
keyboard shortcut.

Remove flatten and try more things
Use switch for Swift 1.1 compatibility
Use JSON enum and function composition
Use if-let for data unwrapping
Fix PR comments
Use subscript with JSONValue
Fixed case sensitivity for file paths

The Xcode project file contained four cases where lowercase  characters
were incorrectly used in file paths.  This breaks on Mac OS Extended
(Case-sensitive, Journaled) filesystems.
Add files to OS X target and fix build
