image-publisher: providing initial recipe

diagnostics: updating to 1.8.10 and adjusting dependencies

In 2014, the update of the diagnostics recipes from 1.8.3 to 1.8.4
failed due to reasons that seem not to be relevant anymore in the
current version 1.8.10. As the diagnostic-aggregator recipe failed
with gcc6 (cf. https://github.com/bmwcarit/meta-ros/issues/392

),
I revisited the diagnostics recipes and this commit updates them.
The current diagnostics recipes in version 1.8.10 do not fail with
gcc6, and is one step forward to build meta-ros with gcc6.

poco: use meta-oe's recipe instead of own one

octomap-ros: solves link issue with liboctomap.so and local ros installation

The meta-oe provides since commit 8700ba38@openembedded/meta-openembedded
(commit date: 2016-01-14) [1] a recipe for the POCO C++ Library.
Consequently, this commit removes the libpoco recipe in the
meta-ros layer.

As meta-ros already depends on the meta-oe layer, the poco
recipe is available in release version since 2016-01-14,
and the poco recipe in meta-ros is redundant for these versions.
However, this commit still provides the currently latest poco
recipe [2] for users that are not using a recent version of the
meta-oe layer.

Updates for recipes in recipes-devtools

The Openembedded Layer Index [1] shows that python-six in
version 1.10.0 is already provided in the openembedded-core layer
and in the meta-python layer, so there is no need for a third copy
of the python-six recipe in meta-ros.

The recipe python-six is provided since commit a36869c7 in the
meta-openembedded repository (commit date: 2015-04-13), and
is provided since commit 9979e35f in the openembedded-core
repository (commit date: 2016-07-20).

In my opinion, at least the commit a36869c7 is far enough in the
past, so that we can safely assume that all new meta-ros use a setup
where python-six is included at least in meta-python.

For users of older versions, we include a remark in the README.md to
allow `git blame` to pinpoint to this commit here.

The recent versions of the rosbridge_library package does not depend
on python-pytz anymore. So, this commit removes the dependency in
the recipe file and removes the now unneeded python-pytz recipe.
