Make default plugin config styling be "panel panel-body"

[Aaron Wells]

The plugin config page's page template is basically just this:

{include header.tpl}
{$form|safe}
{include footer.tpl}

In order for the displayed form to look good, it needs to either be in class "panel panel-body", or be made of collapsible fieldsets. All of the core plugins are either made of collapsible fieldsets, or have "class=panel panel-body" declared at the plugin level, in the "get_config_options()" function for each one.

But third-party plugin developers would have to know to add those two classes. Otherwise, the form is displayed directly on top of the page background, instead of in a white panel on top of the page background.

So what we ought to do, is make "panel panel-body" be the default class for the plugin configuration page.
