When moving a vector, the list order could get confused, resulting in a

segfault, failure to update the screen content, and assigning of invalid 
references.

- gui_tools.c: removed duplicate (harmless) line 
- inst.c: when moving a vector to a new base, we may have to reorder the list
  so that the assertion vectors always follow their bases is still maintained.
