Console: broken doc links

In doing the Edgent rename, noticed two broken doc links in the console samples. In both cases they refer to console/package-summary (package-info.java) info that doesn't exist.

See the samples.console's "Web Console Application" link on this page incubator-quarks/target/docs/javadoc/overview-summary.html

and a similar link in the Description text on this page
