* mostly restored the tiled importer unit tests * code cleanup * code cleanup * almost got tiled maps serialization independent of the content pipeline * refactored the tiled map content importer so that tiled maps can be loaded at runtime * code cleanup * removed nuspec files * experimenting with an XML based GUI markup parser * a few more markup parser features * finally got a working open file dialog * experimenting with markup bindings * attached properties * working on the gui stuff again * working on a better textbox * multiline textboxing * new text box is really coming along * removed the content explorer experiment * restored the old gui demo back to the way it was before (for now)
