This commit adds recipes for rosbridge_suite and its dependencies.
Its main content is based on the commits of pull request #364 by
Christoph Schultz.

As maintainer, Lukas Bulwahn just included the contributions
with a proper commit message, added the new packages to the
packagegroup-ros-world, and slightly improved the line breaking.

The internal CI build detected that bitbake robot-state-publisher
fails after the recent version update. Hence, this commit adjusts
the dependencies to those dependencies stated in the package.xml.

Some of the gst-plugins-good modules were missing to setup a cam for some basic scenarios/tutorials. I added it so they'll be added to the default build set.
