Changed lua table.sort() function to accept any index as a second parameter, if not a function it will assume the items to sort are tables and sort them by the given index
Improved the integrated lua profiler (only works when luajit is disabled)
Greatly improved performance when moving around the map. Map:checkAllEntities() is now much faster, FOV code is also faster
