Hand attached - Githubissues

Removed hand_attached parameter from arm configs
Removed mode and bounds from dynamics_adaptation, class accepts generated intercepts only
Moved triangular intercept code from dynamics_adapation into nengo_extras
added ur5 model
all Mujoco examples run on ur5 and jaco2, just append ur5 or jaco2 when calling an example (Default will use jaco2)

Path Planner API update
- Generate orientation removed from master class of path planners. Now the orientation path planner has a match_position_path function
- all path_planner.generate() must return self.position_path and self.velocity_path
- convert_to_time() will return the interpolated functions, but not save them to self
- using full word position, velocity, and orientation, no shorthand
- examples use transformation.random_quaternion() for random orienatations
- convert to time parameter renaming: pregenerated_path > path, time_limit > time_length
- orientation planner checks if euler angles were passed in instead of quaternions and points the user to transformations.quaternion_from_euler()
- all examples updated and running
