Theme Updates, "Slide" animation, and WIP animations

Switched up the theme for the asset pack page & I think it looks a lot more attractive now at a first glance with the minimalistic look. (check it out!) In the process I cleaned up some older animations here and there but most changes were just an update to the theme and presentation.

Did an overhaul to the side-climb/ladder animation but did keep the old files and animations in there in case anyone preferred what was there already.

"Slide" animation added. I'm also considering like a 45-degree type slide for slopes. Is that even something that is desired? Let me know.

Currently working on the Dash animation (kinda tough to make this look really crisp with no secondary animations like hair/clothes) and a Knocked-Down/Hurt state. The latter should be the easier animation for me at the moment, but look for those next.
