Report asset path errors on CMS rather than just log them

Hi,

problems such as this could be caused by typos' or content juggling:

• 20.09.2012 15:14:22 WARN [org.hippoecm.hst.servlet.utils.ResourceUtils.lookUpResource():174] Node at path '/content/assets/xxx/site/bottomBorderBlue.png' cannot be found.
• 20.09.2012 15:14:25 WARN [org.hippoecm.hst.content.beans.manager.ObjectConverterImpl.getObject():74] '/content/assets/xxx/favicon_xxx.ico' is not a valid relative path. Return null.

It may be handy to alert content authors about these mistakes rather than just log them; a bit like with broken links.

Best,
Edoardo
