Qt: tweak ui files

make about dialog a bit taller for full message on more systems

for direct_connect.ui hedging bets here, there is a text field for port
number that possibly shouldn't be translated, marking as such, but also
adding a translation note for the event that it makes sense to translate
the placeholder text to something other than the default multiplayer
direct connect port.
