add static library project for IASK

* add static library project
  provide proper build settings, formatting, unit tests
* add workspace to repository (combines app + static lib project)
* modify sources to work with static lib project
  the sample project uses recursive-header search paths to find
  IASK headers in the different subfolder (Controllers/.. Models/,…).
  The static lib sample app uses the installed headers which are installed
  in InAppSettingsKit/ subfolder
* prepare unit tests for IASK which will live in the static library project
* static lib project configuration is done in xcconfig files for easier maintenance
allow initialization with a custom NSUserDefaults instance

or something that looks like one. This will allow easier testing
as well as custom NSUserDefaults implementation, subclasses,...
test abstract store

* refactor IASKSettingsReader's initialzer to allow reading from bundles
