Fresh Player Animations

This update fixes the large number of bugs that Fresh Player Animations used to have (these fixes were supposed to have been included in 0.3, but that didn't happen by mistake).

• Fixed the movement of the arms when swimming and crawling (it's the same as Vanilla, for now)
• Hand animations while using items or atacking finally work

Sorry for so long without an update, it's been hard to find free time. Don't worry though, there are still plans to add new animations, eventually improve the current ones and continue to maintain the pack. Thank you for your support and your trust that Fresh Player Animations will turn out as well as possible.
