Fix wineconsole curses bugs

[Jukka Heinonen]

After this patch, it is possible to use wineconsole
curses backend even if your unix terminal is smaller than
user backend size. Previously too large screen dimensions were
passed to prefresh() which made curses stop updating the 
terminal. Also, cursor no longer jumps into wrong place
after printing stuff to screen.




Changelog:
  Wineconsole curses backend now works even if
  terminal is smaller than console size. Cursor
  is no longer left into wrong location after screen
  updates.
