argparse/support are part of core Python in Fedora

Added rosinstall and wstool keys for Fedora

See previous commit for information on why we don't use the rosinstall RPM

Updated libusb-1.0 key for new name in F18

Updated libjpeg package key for Fedora

This was changed in a previous release of fedora, F17 and F18 both use libjpeg-turbo-devel instead of libjpeg-devel
Added collada-dom/libpoco-dev/protobuf-dev Fedora
