Merge pull request #654 from dgossow/hydro-devel

makes read-only properties appear as disabled
rviz should be exporting catkin depends

Without these exports packages which depend on
rviz do not get the correct include directories
and link libraries.

I built this list by finding all of the #include
macros in all the header files, then I looked for
includes from external packages. When I found one
I added to the list of exported packages.
rviz should not create files in the source space

The source space should be considered read-only
as to properly support out-of-source building.
[style] remove trailing whitespace
fix usages of urdfdom, which is not a catkin pkg

urdfdom is a third party cmake package, which
was mistakenly masquerading as a catkin package.
I have fixed that and I have fixed rviz to
reflect this.
Missed a dependency on resource_retriever
Merge pull request #655 from ros-visualization/fix_exported_depends

Fix exported depends
Added check for loading of .vcg files, which are the old format.  Now gives useful error message.
1.10.1
Fixed crash in PointCloud2 display when cloud data is wrong size.
Fixed bug #659, seg fault on some meshes with materials.

Turns out rviz was assuming that submeshes were not re-used, but assimp does allow for it.
With this change, that is supported and no longer causes a seg-fault.
1.10.2
make use of DEPENDS in catkin_package(..)
