Bot: Selection of arrow pre set
 Every Bot got the new trait (actually it's an interface) "IntelligentArrowSelectionEntity". Every method inside is for intelligently selecting arrows. The strength of a Bot can be compared with the enum  BotStrength. Make sure, you've the correct java version as I'm using default-methods. SCALA seems not to now default  methods, because he marks it as an error, but it's working perfectly.
