Added support for adding appwidgets beyond clock and search to the
intital configuration. Also pulled in a previous change in Launcher that
allowed http shortcuts. New syntax looks like this in
default_workspace.xml:
<appwidget
launcher:packageName="com.android.settings"
launcher:className="com.android.settings.widget.SettingsAppWidgetProvider"
launcher:screen="0"
launcher:x="0"
launcher:y="2"
launcher:spanX="4"
launcher:spanY="1" />
<shortcut
launcher:packageName="com.android.settings"
launcher:icon="@drawable/ic_launcher_appwidget"
launcher:title="@string/group_folder"
launcher:uri="http://www.nytimes.com"
launcher:screen="2"
launcher:x="2"
launcher:y="2" />
