Match bemenu's --monitor behavior

[maribu]

• bemenu defaults to -1 (a.k.a. "focused") for the monitor, but pinentry-bemenu defaults to 0
  • this is highly confusing if currently working on monitor 1, but the prompt is appearing on monitor 0 instead
• add support for "focused" as alias for -1 and "all" as alias for -2, as bemenu does
  • adding --monitor all is simply easier to understand than --monitor -2

Thanks! Unfortunately I can only take a proper look at this in a few days.

FYI I am working on exposing the option parsing from bemenu so it can be reused by pinentry-bemenu. Then the inconsistencies should all go away.

Thanks :) And thanks for developing this in the first place!
