Add parts that require flipping

[Brian Gerkey]

• Need to identify which part will be flipped. Needs to be tall to allow gripping from the side.

• Need to update scoring system to consider full pose: wrong roll/pitch orientation will result in no orientation point(s) because being off by 180 degrees it beyond the orientation tolerance.

• Also need to verify that this two-step process is feasible.

I merged https://bitbucket.org/osrf/ariac/pull-requests/46

still todo: add flippable part, integrate it into this config file, update this page to explain flipping specification

[Carlos Agüero]

I just tweaked the pulley_part to be used as a flippable part and updated the qua3b config file in pull request #52. The frame_especification instructions have been updated too.
