Feature request - Number of tunnel entries in root of tray icon context menu

[Jason A. Donenfeld]

Hi,

I don't want to add a knob for this, but I would take a patch that
uses a smarter heuristic than just "10". Feel free to send patches to
the list. The code in question is here:

https://git.zx2c4.com/wireguard-windows/tree/ui/tray.go#n225

For example, if you can calculate the number of entries that can fit
on the vertical height of the screen, maybe take a third? Or two
fifths?
