Rename tui_suppress_output
This patch renames tui_suppress_output to the more descriptive
tui_batch_rendering. This code was never really correct, and was
based on a misunderstanding of the curses API. The updated comments
describe the intended use of this class.
This also removes the erroneous tui_win_info::no_refresh.
wnoutrefresh does not prevent any output; rather, it copies from one
curses buffer to another but (unlike woutrefresh) without then
flushing to the screen.
tui_batch_rendering now works in the correct way: calling doupdate in
the destructor of the outermost instance, thus batching all screen
output until that point.
The patch adds instantiations of tui_batch_rendering to various spots,
to make sure it is active when refreshing.
