Fixes #176: Bug when saving recently edited army
* Add loaded file cleanup to AbstractWarFoundryFactory
* Add override of method with Zip reference closing to WarFoundryXmlFactory
WarFoundry now no longer ends up with trailing handles to files, although why they only caused problems in some situations is unknown
Also:
* Some line ending fixes (curse cross-platform development and different line terminators!)
