Website improvements

This is just my opinion and I get it can be different for other people, but here's a couple things I'd implement:

- Episodes list on Anime/Info page
- Next episode block on Anime/Info page
- Number of episodes released / Total episodes on anime info left block

This picture is a real working solution I did myself with some js

Thanks! 😊
PD: I got also some css improvements but that's just my style preferences stuff
