Panels views block delta different from Views block delta

In panels_views.module, the delta generated for views blocks are different then the delta generated by the Views module.

In views/plugins/views_plugin_display_block.inc:

$delta = $this->view->name . '-' . $this->display->id;

In panels/panels_views/panels_views.modue:

$block->delta  = $view->name . $display;

This has caused some problems with rendering content via the "System Block" panel style, which gets passed to block.tpl.php. The most glaring problem this causes is a different block #id for views blocks passed through panels.

Attached is a patch to fix the problem.
