A lot more things

- Moved scan button to inside the home screen
- Added items screen
- Scanning functionality updated to work with BEms
- Different home screen layouts depending on the configuration (BE with BEm, BE with DIm, since they don't have the same data, looking at you, special training)
- It is now possible to import BEms
- Character size is now more accurate, (no more big babies)
- Once sent to the watch, characters are deleted from the app, and it shouldn't fail
- Updated domain model to support evolution history.

TODO:
- Reorganize some of the code, mostly SQL queries and reorganize the scan screen functionality
- Create home layout for the VB watch
- Start figuring out reading data from the VB
    - Also create VB data domain model
    - Also start figuring out writing to the VB (it's 3 steps)
- Block off scan button until secrets are imported
- Start working with the dex
    - Update domain model
    - Use cfogrady's blank character when not seen
- Cancel character upload in case the app database does not contain the card for it (otherwise, the watch will delete the character)
- Export character data (in case of any app issues or changing phones)

(Also added some more icons)

Woo
