## Summary

Addresses
https://github.com/crosspoint-reader/crosspoint-reader/issues/504

- Reverts book progress % to showing as an integer instead of with a
decimal place
- This was changed to 1 decimal point of precision in
https://github.com/crosspoint-reader/crosspoint-reader/pull/232 from
what I can tell
- As this wasn't the primary intention of that PR, I'm assuming it was
left in accidentally

IMO having a decimal place of precision is too much for something as
vague as book completion percent. This de-clutters the status bar and
prevents extra updates as you change pages.
