Extension updates made easier

Tired of having to manually update an extension and breaking your menu links? As of Joomla 1.5.5, you no longer have to use the installer to first uninstall an extension and then reinstall a new version. A new feature from Sam Moffat was committed to the codebase that allows developers to use <update> in their XML. You'll be able to install the new version without removing the old one, preserving all of your menu items and other settings.
