Corrected UR10's urdf to faithfully represent joint effort thresholds, velocity limits, and dynamics parameters.

Corrected effort thresholds and friction values for UR5 urdf.

Issue#24 - made change to driver.py s.t. test_move.py is now functional.  Thanks for the contribution!

Arguments were previously "in order" but the keyword arguments are recommended as they are more resilient to msg changes.

Added definitions for adding tergets in install folder. Issue #10.

Corrected warning on xacro-files in hydro.
