Formatted according to
https://github.com/Bukkit/Bukkit/blob/master/CONTRIBUTING.md#code-requirements

Not an indepth formatting endeavor... just a quickie job to make try and
follow Sun/Oracle/Bukkit code conventions.

By 'quickie job' I mean:
Control + A
Alt + Shift + F

To 'select all' and 'format'

Basically, removing tabs and organizing imports. Nothing more.
ArenaSpleef v1.5.2

Just updated the POM to newer versions of Bukkit and BattleArena.
