major enhancement to roadmap support

Hi everyone, Good news. If you log into pear.php.net, check out the homepage for your package under the "Current Release" section. Click on "Development Road Map" and then add a roadmap (it can be deleted later, so anything will do). Note that release date can be anything understood by strtotime(), so "+3 weeks" works as well as "Next Saturday" or "2007-03-05". Finally, click "Add Bugs/Features to this Roadmap." For a sample of what occurs, see http://pear.php.net/bugs/roadmap.php?package=PEAR&addbugs=1&roadmap=1.5.1 A concise list of bugs and features which includes all open bugs plus suspended bugs (you may wish to add suspended bugs to a future version to keep from forgetting them). This makes adding and removing items from your roadmap extremely simple. There are also links to and from the bug tracker to the roadmap. Thanks, Greg
