Show list of dependent projects

Since resolution of http://jira.codehaus.org/browse/CONTINUUM-58 continuum builds dependent projects when an upstream project has changed.

However there is no (easy) way to get a list of dependent projects, there should be the inverse of "Dependencies" shown in "Project Information". This feature is needed for example if after updating the version of a project one wants to update the dependency in dependent projects (and possibly update the version of the dependent project). A similar feature is implemented in Hudson.
