Add a procedure blocks to get the amount of XP of a player and Add/Remove amount of XP procedure blocks

Issue comments

Hmm... I think imho that procedure blocks like "getPlayerExp" and "setPlayerExp", should get work. And with extra option "p" (for directly exp points) and "L"(for levels) yet.

This will be great solution for exp storaging and other events/operation where exp points is a cost, ex. teleportation or use a special item.
