[Patch] Feature Update (Elapsed and Remaining Time) and Bug Fix for Console_ProgressBar

Hi all- Thanks for the excellent CLI progress bar for PHP! I am using it in a long-lasting import script. I added a couple of output options: %elapsed% The elapsed time in HH:MM:SS format. %estimate_remaining% An estimate of the time remaining in HH:MM:SS format. Based on a moving average. The estimate remaining is calculated through a moving average algorithm of the last 5 measurements so that it "corrects" itself over time. There's obviously no perfect way to estimate time remaining, but at least it's a bit more realistic than using a average for the whole run. Also I fixed a bug with some chars not being erased in ANSI mode if the repaint str is shorter than the previous display. This fixes the bug I just reported: http://pear.php.net/bugs/7407 All the code keeps the same style as the original and is fully commented as well. Enjoy! Alan Pinstein
