Description:
------------
I needed to change timeout of getch() on a particular window, not just the 
standard window.  So I created the included patch to add this support. This was 
accomplished by wrapping around ncurses_wtimeout.


Test script:
---------------
<?php
ncurses_init();
ncurses_cbreak();
ncurses_noecho();
$window = ncurses_newwin(10,10,0,0);
ncurses_timeout(1000);
ncurses_wgetch($window); // will wait here until button pressed.
echo "not reached until after character";
ncurses_delwin();
ncurses_clear();
ncurses_refresh();
ncurses_end();
?>

Expected result:
----------------
on the ncurses_wgetch($window) line, it will wait and not honor the timeout.
However, with the patch and replacing:
ncurses_timeout(1000);
with:
ncurses_wtimeout(1000);

It will stop looking for input after a second, which is the desired effect.
