Animal Fun - Prehistoric

v1.4.10 -- Thank you Jessica and MarkCraft for staying up with me all night to fix these! Also thank you to everyone on my test server for all the rigorous testing; I appreciate it greatly!

• Fixed the marine reptiles that never swam.
• I believe dimorphism and some coloring has been corrected. I only checked one but the rest should be fine. It doesn't apply to all animals here anyway.
• Added some additional animations for various poses. Please tell me if they aren't realistic or if they are just weird. These guys rested too even though some of them rested upright but not all of them!
• Adjusted the movement mechanic quite a bit. They were doing the cartoon run where the legs were running but they weren't getting very far. This should all be corrected and match the ground they are covering during movements.
