Added a very beautiful profile menu (That displays all of your kitpvp statistics, incluinding the levels represented in a yellow glass pane. Also i have added kdr status in the profile menu and xp to next level. (For now it only displays in the glass level 1 to level 14) also the glass tell you what level you are and if you reached the level displayed on it - Screenshot of the menu:

Added %kp-pvp_player_xp_to_levelup% placeholder that displays the amount that player needs to levelup to the next level.
Fixed some bugged message in 1.14-1.18 plugin version.
Now /stats displays the profile menu instead of chat. (You can also see other players profile! (Need permission kitpvp.stats.see.other)
