Renamed the commonly used Position POJO into AdvancedPosition, as it also hold pitch, yaw and roll

Made GuiDropdown only accept instances of GuiEntryListEntry to avoid unneccessary toString() methods returning the name
Added GuiEntryListValueEntry which holds a Value and a Name to be displayed
Continued work on GuiObjectManager
