New environment animations

Hello my friends!

This update there are wooden doors with opening and closing animations and prison gate opening animation with all VFX separated in case you want to use it without the effects. Blood pool tiles with spikes are also in this update., as usual, Its tiles animations are already setup in TiledMap Editor and ready to use.

I'll now work on the characters for this pack and I'll start to release them in the next updates.

Thank you for your support!
