Changed much of the mergetag structure and some functionality. First tests on windows. Changes to mergetag Reader methods. New functionality allowing a dataSecCreator to cause sections to be skipped. Moved several of the mergetag modules and some of their contents around. Moved all interfaces to separate modules in iface/ . IReader & IWriter interfaces exist; MTTReader, MTBReader, MTTWriter, MTBWriter & DualWriter all now exist and implement IReader/IWriter (although the MTB variants are dummy classes); makeReader & makeWriter should both be fully functional. Tested building on windows with partial success (works but window won't open). Included a temporary hack from windows to get supported resolutions information. committer: Diggory Hardy <diggory.hardy@gmail.com>
