Wrye Mash 87

• Updated 7zip files
• Wrye Mash will remove plugins from Data Files when uninstalling
• Temporarily added pubsub from wxPython for WMSA
  • When pubsub isn't present the following error occurs:
  • AttributeError: 'module' object has no attribute 'Publisher'
• Fix for bolt.Path.getNorm on Python 2.7.8
  • Would return a Path object if it was of the form Path(u''), apparently Path(u'') now is True for if not name, prior to this is was not.
