enhancement: editor show droid corpse trap association to meleecontext

[ghramsey]

When looking at something like a droid corpse trap the editor does not show that there is an associated meleecontext_corpse trap instance.

The two entities do not show links directly. The meleecontext instance is by association only b/c ithe coordinates overlap
with those of the droid corpse. Can you add some method to "see" this association? When I edited a corpse trap it took
a lot of investigations to decipher how it knows to grab you. Thankfully the traps are labeled plainly "meleecontext_corpse trap",
but unless one knows to look for them the association is unknown as neither entity shows the connection.
