Curses: fixed mouse interactions on PDCurses

* There is yet another PDCurses vs. ncurses incompatibility:
  ncurses has a mouse event queue so you must call getmouse() repeatedly
  for every KEY_MOUSE, while PDCurses apparently doesn't queue and would
  end up in an infinite loop. I.e. the program would hang once
  you press any mouse button.
* This forced us to add an PDCurses-specific version of teco_interface_getmouse().
