Basic saving and loading

- You can finally save and load your different styles!
- Brand new icons from Font Awesome!
- The clear button was refreshed and replaced with the trash can. While I've never gotten complaints about the interface, this should prove to be less confusing.
- Clear button moved next to save/load.
- Introduced a basic indicator when loading and saving
- Bumped version to 1.10
