Loading octomap_monitor optional in planning_scene_monitor WorldGeometryMonitor
Python wrapper for getEndEffectorTips()
Added wrapper for new function
Merge pull request #484 from davetcoleman/python_get_end_effector_tips

Add python wrapper for new robot_model function getEndEffector tips
adding PoseStamped topic to move the interactive marker from other ros nodes
such as joystick programs.

Added field next to planning_time for planning_attempts
Now, ParallelPlanner terminates either due to timeout, or due to this many attempts.
Note, that ParallelPlanner run's Dijkstra's on all the nodes of all the sucessful plans (hybridize==true).
moved planning_attempts down one row in gui to maintain gui width
Removed PlanningContext clear before planning call
returning int values
motion_planning_rviz_plugin: add move_group namespace option

This allows multiple motion_planning_rviz_plugin /
planning_scene_rviz_plugin to be used in RViz and connect to
differently-namespaced move_group nodes.
remove leading '/' from DEFAULT_PLANNING_SCENE_SERVICE; otherwise planning_scene_rviz_plugin fails with 'Failed to call service /get_planning_scene ...' if move_group is in a namespace different from '/'
service must have access to global namespace
Made loading octomap_monitor optional in planning_scene_monitor when using WorldGeometryMonitor
add checkbox to toggle if moveit rviz plugin subscribes
the topics to be used for communication to the external ros nodes.

update moveit_joy.py to parse srdf to know planning_groups and the
names of the end effectors and support multi-endeffector planning groups.
Documentation
Update joystick documentation and rename the
the launch file for joy stick program.
Shorten the message the check box to toggle
communication with joy stick script.
