Player Fixes

:white_check_mark: Fixes
• Commons-Lang reference not working (Bukkit references 2.3, we require 3.1. Exceptions are thrown when attempting to use Bukkit's.)
• Fix NPE when setting speed (seen during restoration from persistence/disk.)
• Fix replacement networking code not being assigned before Bukkit calls, leading to an NPE. (#74)

Tested working on Bukkit 1.7.2-R0.1 (Build #02943) with creation and persistence.
