This commit does 4 things:
* It increases the default small size of the NetPlay window to a larger
and more appealing size.
* It cleans up and reorganizes a bit of the NetPlay Setup UI code.
* It moves the Direct or Transversal Selector to be more appealing and
nice looking.
* The Direct or Transversal also gets a label and nicer text, and a
spacer.
This is only queried, there's no need to expose it for writing.
Even if it was written to, a data member shouldn't be part of
your public API unless its part of a dumb object or trivial struct.
