Other few things

- I changed more things to flows from the database
- Cleaned up the logic coming from the scan screen
- Added a delete button to a character. CAREFUL, IT HAS NO CONFIRMATION YET!
- Fixed a few things, now scanning is more stable and will fix the second whoops thing.
- Quick patch, should improve stability when writing to the watch
