Small code cleanup
- Removed unused vars from the slope struct. I'm pretty sure they were meant for something at some point, but right now there's nothing using them and frankly I find it hard to understand what they were meant for. - Removed unused slope flags. - Flipped dynamic slope flag naming convention.
