Kindly Clean up part PAW/RMB when removing crew

I've been testing MoarKerbals - and with the aid of this great mod, been xferring excess kloned/kuddled crew off the ship in order to make space to continue testing and debugging.

I've noticed that the PAW/RMB for parts gets clogged up with kerbal inventory slots (named) for crew that have been transferred.
call it Ghost Inventory

to recreate:

1. go to flight with a crewed vessel
2. use SM to remove crew from part/vessel back to the AstroHut
3. the group (inventory) in the RMB/PAW of the part the now removed crewmember was from still has their inventory.
