reconfigure_gui: Scroll-bar ranges now limited to 5 significant digits.
reconfigure_gui: Turned off non-linear scrollbar scaling for finite-range parameters.
driver_base: Allow the standard diagnostic status to be extended by the particular driver.
driver_base: Improved error message logic to avoid printing errors in non-error conditions, and to print errors when they recur after a period of recovery.
driver_base: Hold the lock during self-tests. Avoids deadlocks when dynamic reconfigure is attempted during a self-test.
Uses the ROS SIGINT handler to allow CTRL+C to work at all times.
Documentation review completed.

reconfigure_gui: automatically reconnects in a node is restarted.
reconfigure_gui: layout improvements.
reconfigure_gui: prints a message when it is launched.
dynparam: set_from_parameters warns if no parameters are found on the server.
dynparam: handles invalid input more gracefully.
dynparam: warns if it can't connect to the server.
dynparam: can handle yaml.
dynparam: paramset command is now get_from_parameters.
dynparam: fixed broken import.
python client: timeout=0 does not block.
python client: find_reconfigure_services returns a sorted list.

driver_base: Removed obsolete services (were an early attempt at dynamic_reconfigure).
