Re #176: Bug when saving recently edited army
* Try to make sure that we clear up more of our open streams
Bug seems to be state related in some way since I can only trigger it when loading the file as the first action, but doesn't seem to be related to file loading of other data files since a diagnostic hard-coded "LoadFiles()" call in the FrmMain constructor doesn't change the behaviour
