Allow to specify '^' at the end of stat name to designate that it should be sorted in ascending order. Similarly, allow any of 'v', 'V', '.', '!', or '_' suffix "symbols" to designate descending order. It's such a zoo for descending order because there is no single intuitive symbol that could be used (using 'v' looks pretty weird in practice), so few symbols that are "downwards leaning or pointing" were chosen. Either way, it shouldn't cause any troubles in practice. This new feature allows to customize sortering order to match user's needs.
