New features and fixes

[ThaBalla1148]

Implemented HiddenCommand annotation for CommandExecutor methods

• Using this annotation allows commands to either be hidden from help command and auto-complete or disabled from being executable. Supports both simultaneously.
• By default, hidden commands are executable, but are hidden from displaying.

Moved logic for CommandExecutor.print() to Console.printCommands()

• This was done to better support the new HiddenCommand annotation

Fixed console not being disabled while not using GUIConsole if disabled flag was set

Refactored and updated method and argument determination/parsing code

• Now supports String, Boolean, Byte, Short, Integer, Long, Float, Double, and their primitive counter-parts

Updated Box2DTest with HiddenCommand methods

Added ConsoleTest

• Tests all supported Command argument types
