Merge branch 'is_reachable_bugfix_2' of github.com:mbforbes/pr2_pbd into gui
Rainbow markers (excluding green) and a failed legend (so far).
Taking out the legend experiments to move on to other GUI changes for now.
Change background color from 48,48,48 to 175,175,175 so that it is lighter so that dark text shows up better on it. Can't do bacgkround color for text labels, and PR2 is already white, so a light background and dark text seems like the best option.
Make the text larger, match the (rainbow) colors of the pose markers, remove the transparency, and add a space between 'step' and the number.
Add (static) orbiting to labels.
Make surface grey; untested because scanning for objects isn't revealing anything...
Make link arrows (connecting poses) scaled to be shorter so you can see the 'arrow-ness' of them; also make them more yellow and less transparent to be more visible in general.
Make object reference arrows more green (like objects); TBD whether this is helpful, as object scanning not working in simulation.
Separate rainbow colors into two hands (yellow -> red for right hand, cyan -> blue for left hand); make arrowheads of links between poses larger.
Add two icons that represent 'completed' tasks; start modifying the GUI by adding three slots for actions.
Merge branch 'groovy-devel' of github.com:PR2/pr2_pbd into crowd-gui
Merge crowd-gui (and thus gui-rainbow-markers) into mock-objects.
