This small commit is to use the panel_link to reduce some code.
This commit is based on an excellent suggestion by jsherrill to leverage the navigation_element in the panel.js to handle the new link added to the System Groups -> Details pane. The navigation_element was originally added when we needed to support 3rd level navs within a panel (e.g. to avoid the normal redirect that occurs when a user clicks a link in the 1st or 2nd level nav); however, it is actually something that can be used by any link on a pane where do not want to leave the page and basically want to go to another pane. As a result, renaming it to panel_link.
When a user invokes 'system_group info' on a group, include in the response the number of systems currently assigned to it.
Adds back template rendering test case for change password.
