XP Level placeholder

[crispycrafts]

I would like to request the addition of a new placeholder, [xplevel], that returns the player's experience level. Currently, we have placeholders for total experience and experience progress, but having a dedicated one for the level would be very useful for various display scenarios.

Issue with lvl is that its not static and depends on level differences, for example level 2 needs only 9 exp from previous, while level 30 needs 107. So one level isn't really equal to one level. Maybe we could have special one to just indicate how many levels player lost in a sense that level changed from one to another, while at same time it would not really indicate much as you can go from level 64 to 63 by spending single exp point, while for level 64 you would need 424 exp points.
