Preparing for initial release

[Muqsit]

Before releasing this plugin on poggit, I'd like to address a few things:

• The plugin excessively uses reflection, sometimes in places where reflection may not even be necessary (see Loader::addPlayer() for example).
• Only one FakePlayer spawned? #15 - To a non-developer (or a non-programmer rather), this plugin is delivered mostly static as it lacking commands. Players cannot be spawned without modifying the configuration pre-startup.
• Document default behaviours (see default registered behaviours: FakePlayerBehaviourFactory::registerDefaults()).
