cmake-gui: Add --install option to add command-line tools on OS X 

On OS X add an "--install[=/path/to/bin]" option (defaulting to
/usr/bin) that installs symbolic links into the given directory.
This will help OS X users make the tools available on the command
line even when they sit inside a CMake.app bundle.
