Prevent flickering when redrawing the TUI python window

Browse source 
tui_win_info::refresh_window first redraws the background window, then
tui_wrefresh draws the python text on top of it, which flickers.

By using wnoutrefresh for the background window, the actual drawing on
the screen is only done once, without flickering.
