Add Flipswitch library and headers (version 1.0.2)

Template coming soon.

Side note: I know @iMokhles already submitted a pull request for a Flipswitch template (:thumbsup:), but my idea is a bit different. I'm working on overhauling some bundle templates to let iOSOpenDev targets benefit from the full Xcode build process, e.g. automatic xib compiling, binary plist/strings conversion, and PNG optimization.
