Replace New dialog box with separate tools for resizing maps and replacing terrain textures, to provide more power and to simplify the problem of initialising map settings. Fix engine to cope with dynamic map resizing. Add JSON support to AtObj, to let C++ interact with JSON more easily. This was SVN commit r9566.
