Cargo - Remove cargo objects from zeus editable objects

[johnb432]

When merged this pull request will:

• Title. I found it mildly annoying to see ACE cargo objects attached to the vehicle they belong to in the zeus interface.
  This only applies if the ace_zeus component is loaded
• QGVAR(addObjects) and QGVAR(removeObjects) event in the ace_zeus component can now accept an array of curators instead of just a single curator or all.
• I have tested this in SP only. I imagine it should work fine in MP, but I don't know the locality of objectCurators, as the wiki doesn't mention it.
