A massive overhaul/rewrite for the gui's data management and setup code. Currently much that was working is broken. imde's classes are created in a static this instead of mde's main. gl setup code moved from gl/basic.d to gl/draw.d mergetag.DefaultData: now HIGH_LOW priority instead of LOW_HIGH. Reduced type list to only used types; small fix for indent function. setup.paths: new NoFileException thrown instead of MTFileIOException
