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.

Resolves error:
ImportError: No module named wx

This commit updates to 1.10.17 and removes the local patch that
has been added to 1.10.17. The new version of collada-urdf has
added another target, and its recipe must be updated.

After configuring collada-urdf, the recipe modifies the generated
files to address the problem in #175. However, it does not solve
the root of this cause.

robot_model contains packages for modeling various aspects of robot
information, specified in the Xml Robot Description Format (URDF). The core
package of this stack is urdf, which parses URDF files, and constructs an
object model (C++) of the robot.
