Patch to add hook_panels_views_alter since views_alter hooks don't apply to panels

I'm not sure if this is the best way to do it, but I needed to alter a view that was being displayed in a panel before the $nodes list is generated, normally done with the hook_views_alter* functions.

This patch adds a simple hook to alter panel_views before they are rendered...
