Show XP this level on experience bar instead of total XP

[James103]

Currently, the game shows your total XP earned over the total XP required to get from level 1 to the next level. I would like it if it instead showed your XP for this player level over the XP required to get from your current level to the next level, like most other games with XP systems have. Example: Instead of showing something like "405555/500000XP", it should show "555/10000 XP". The total XP earned should still be accessible, just on the statistic UI instead (#10).
