Main: Rework storage controller handling to allow an arbitrary number of different storage controllers and remove code duplication:

  • XML format changed
  • New StorageController class
  • Removed SATAController (obsolete)
  • Removed the IDE controller code from BIOSSettings, handled in StorageController now
  • 屬性 svn:eol-style 設為 native
  • 屬性 svn:keywords 設為 Author Date Id Revision
