    CMake: Build a complete application bundle on OS X.

    Run osx-app.sh by default on OS X. Aside from giving us a fully portable
    application bundle after building this should let us clear our library
    path at startup should the need arise. Change the name of the osx-app
    target to app_bundle.

    Search ../Frameworks before ../lib. Create PkgInfo at configure time
    instead of compile time. Build our program list as we go.
