I made changes to the URDF parser so that it can handle package names and directories correctly (thanks @ehuang3 for the info), and while I was at it, I found that the parser was rife with poor error handling (including memory leaks and poorly explained exits) and screwy formatting, so I fixed some of that as well.
Now the URDF parsing can handle arbitrarily many different packages (instead of assuming that all resources will be in the same package), but it still depends on the user to specify the paths to the package directories.
I also added the ability to parse raw xml strings instead of only allowing xml files.
Note that there was a necessary API change in order to support multiple packages. This will not affect any users who were not using URDFs with ROS packages in the first place.
