Cleaned up Set::Styling/Card::Styling by spliting that functionality into a 'DelayedIndexMaps' class;

Added 'right' and 'bottom' properties to style as an alternative way of specifying width/height;
Added content_width, content_height and content_lines properties that give feedback on text rendering;
Always show warnings when showing errors and vice-versa, this prevents script errors from appearing before the reader/parse error that caused them;
Finally some preliminairy work on export templates
