update v39.7

The gym is the last one to get a revamp, after that I'll add some new stuff until we hit the 400th! 

 - 

 - Added a simple swing animation to all the 3 hanging punching bags (both to the left and to the right)
- Revamped the cyclette (2 variations)
- Revamped the tapis roulant (2 variations)
- Added an animation to the tapis roulant while it's on

*Everyone who already bought the asset can get the new stuff for free

See you and happy game-making! :)
