/target, /assist and /follow, and right click opens a clam

- /target and /assist find units by name like the original, and /follow walks you behind your target
- right click opens clams and lockboxes, and the tooltip promises it
- the freeze thaws clean, poses release instead of sticking, and you drop to neutral standing before it grips
- unit frame art layers over the bars like the original
