This commit also adds cmake-modules to the dependencies of
clear-costmap-recovery, while looking into an build issue of the
intermediate version 1.11.12(!) of navigation.

The urdfdom-headers package was removed from packagegroup-ros-world
in #182, because it is an empty package and causes the image
creation to fail (cf. #177).
In commit 9ff8d1f7, urdfdom-headers
was added again while adding new ROS packages to
packagegroup-ros-world. As part of the manual regression testing,
executing 'bitbake packagegroup-ros-world' for the different qemu
architectures, but not building full images, this problem has
slipped through the regression testing the last few months. This
issue was reported on the meta-ros mailing list by Parag
Batavia [1].

In commit 53796fc4, bitbake fails at parsing. It slipped through,
as I did not invoke any testing before submitting 53796fc4. This
commit resolves the obvious shortcoming.

The description is not indented after line breaks. All other
information, i.e., the dependencies and SRCURI, are indented with
four spaces after line breaks. Shell scripts are indented with
multiples of four spaces.

In recipes-ros, I located and checked for tabulators and spacing
with these bash commands:

egrep '^ [^ ]+' . --exclude *.patch -R
egrep '^  [^ ]+' . --exclude *.patch -R
egrep '^   [^ ]+' . --exclude *.patch -R
egrep '^    [ ]+[^ ]+' . --exclude *.patch -R

While going through the recipes and manually improving the layout,
I also adjusted the descriptions to use maximal 100 characters
per line.

After running oe-stylize.py on all recipes in recipes-ros, this
commit improves the formatting of some recipes.

To achieve this, I executed these commands in recipes-ros:
find . -name *.bb | sed 's#\(.*\)#./oe-stylize.py \1 > \1_sanitized#' | sh
find . -name *.bb | sed 's#\(.*\)#diff -Naur \1 \1_sanitized#' | sh > diffs

Then, I manually inspected the diffs file, and improved the
recipes.

For the DESCRIPTION line in the addressed recipes, the line width
of 100 characters was chosen, as the LIC_FILES_CHKSUM line and
SRC_URI line usually are also around about 100 characters long.
Hence, choosing a shorter line width, e.g. 80 characters, would
have only created more line breaks, but not reduced the need to
use a file viewer with which 100 characters line width can be
displayed. For the github file and diff viewer and most editors
on reasonably-sized screens, 100 character line width is no
problem.

This version fixes build problems with a ${prefix} other than /usr.

Executing 'bitbake packagegroup-ros-world' showed the warning:
WARNING: QA Issue: image-rotate rdepends on nodelet but its not a build dependency? [build-deps]

On a clean build, 'bitbake image-rotate' failed with:
|   Could not find a package configuration file provided by "nodelet" with any
|   of the following names:
|
|     nodeletConfig.cmake
|     nodelet-config.cmake
|

Hence, this commit adds the missing dependency on nodelet.

It seems as if the archive was updated at some point in time
without spending a new version number. This commit was needed
after I cleaned all downloads from the meta-ros layer.

The patch provided upstream is part of 1.0.7 and hence is removed.
