Bukkit

• adapted to Minecraft version 1.3.1 (new experience system)
• fixed experience not being visible to the player on respawn
• fixed experience rounding issues (credit to desht, whose ExperienceManager I used)
• made the position of saved items be restored (including armor being put back on)
• enhanced loss-percentage to a new algorithm
• minor code changes

• when using Essentials' feature of giving back experience, players get back more experience than they initially had, because both plugins add exp.
• experience is sometimes not updated properly on respawn

This was fixed in v1.81.
