Core code for cmdModuleStashlist

Implement 'stashlist' sub-command. Rely on cmdModuleSavelist but adapt
this procedure to make several behavior changes when called by
cmdModuleStashlist:

* elements are sorted in reverse order
* element index starts at 0
* when no collection target set, only return collection without a target
  set
