Dragon Mounts r44 for MC 1.8.9

• Added custom dragon egg block, which has variants for each dragon breed and is also selectable from the creative inventory (the vanilla dragon egg block behaves like an "Ender" breed egg).
• Reworked dragon entity movement code to fix some oddities when flying.
• Flying dragons now use proper A* pathfinding like on ground.
• Improved dragon controls, which are now more intuitive and consistent when switching between flying and walking.
• Removed dragon control keys R and F. Players can now control the dragon with the normal movement keys.
• The carrot on a stick no longer has any effect on the dragon flight controls.
• Forest dragons now also leave a trail of mushrooms on dirt and flowers on grass.
• Dragons no longer follow their owner in close range. Instead, they try to stay in a larger area around their owners unless they're leashed.
• Removed broken "global" chat command parameter (commands still are global when issued from the server console).
• "/dragon tame" now accepts an optional parameter to set the name of the new owner.
• Fixed baby dragons not being classified as children by Minecraft correctly and being saddleable and ridable as a result.
• Fixed compatibility issues with JourneyMap and other mods that use the entity renderer during initialization. (#22)
• Fixed compatibility issues with Orespawn and Elysium by adding an option to the config to disable vanilla dragon egg interaction. (#7)
• Fixed some dragon sounds played with the incorrect pitch and/or volume.
