adjusting the README; a first try for cross-compiling the cpp-common things; extending the install-fuerte script

we patch catkin as catkin assumes that every linux is an ubuntu system but the openembedded linux system is not

catkin recipe missed to add the python modules to the packages (NB: QA still mentions so files not shipped)

improving catkin recipe so that it does run through (it compiles and installs now, but I am not sure if the installation is correct)

improving dependencies in the python recipes; simplifying core-image-ros after dependencies are improved

adding dateutil to the image, as i do not know why RDEPENDS does not ensure that dateutil exists in the rootfs

tried to add python-vcstools via dependency in python-rosinstall but it does not do and then added it the core-image instead; tuned layout and order in core-image

adding the recipe python-vcstools, as now that the python recipes do not use setuptools to get all the dependencies write we need further recipes

adding the setuptools class from openembedded classic; adjusting the packages; adding legal statement
