Add attribute to mark parts of install tree unstable

This commit adds new AllowUnstableComponents configuration. Setting
AllowUnstablecomponents to true in config.xml will
* allow installing other components when there are errors in scripts
* allow installing other components when there are missing dependencies
* will mark the 'broken' components uninstallable in treeview
