Link that pops up a dialog containing contextual help for a component.
Usage:
new HelpLink("theHelpLinkId", getPage()).setDialog(thePopupDialog)
<fieldset> <legend> <span>...</span> <a href="#" wicket:id="theHelpLinkId" class="help-link"></a> </legend> </fieldset>
Help content of the dialog is looked up as a resource in the i18n GEoServerApplication.properties file. One key is looked up for the help title and one for the help content itself:
..help.title=... ..help=...
