[kinetic] Remove dependency on ros_controllers metapackage.

As per http://www.ros.org/reps/rep-0127.html, packages are not allowed to
depend on metapackages.

Fixup for MoveIt! Kinetic

Micro-revert of #251.

If dependent xacros include the ur* urdfs, but don't use Jade+ xacro, 'pi'
will be undefined otherwise.

And remove gazebo_ros_pkgs, as it is a metapackage.

Instead, depend on the individual plugin packages needed.

Fix xacro warnings in Jade

Depend on new moveit_kinematics pkg now that MoveIt has moved the kinematics plugins.

Add prefix parameter in common launch

Adding joint limit variables in .xacro.urdf files

We want to set a prefix when starting the ur_common.launch, so we add
the prefix argument and set the parameter for the driver.

Updates from latest release

add missing dependency for moveit_simple_controller_manager

travis support for indigo

Ur kin constants

Moved SetIO FUN constants from driver.py to relevant srv file
