4.6.0: Font and/or installation issues on Windows

[Timo]

It's advised to reboot your Windows computer before installing version 4.6.0 (or newer) after using version 4.4.0 or 4.2.0.

Versions 4.4.0 and 4.2.0 would install some fonts globally on startup. This was a mistake from me for two reasons:

- The fonts had some rendering issues in the pedigree
- The font files would be locked until the next reboot and start of Pigeon Planner

The last point means that uninstalling those version might cause issues as the files couldn't be removed or replaced. Rebooting the computer will release them.

Thank you, Timo! It's working fine after the reboot. Love it! You definitely are a game-changer!
