Two features: page menu and custom filters

Add all reports dynamically into the page menu. The layout xml will unset the original page menu block and adds the clean page menu block. If you find any other possibility for injecting dynamic menu items let me know asap :-) You have to clear the cache if you change the title or add/remove a new report.

Second feature adds the possibility for custom filters for columns in the Report/View/Grid.php file.

Auto reformatting also removed some superfluous whitespaces / tabs ;-)
@SchumacherFM do we need all this logic in here or can we just do something like.

    $array = parent::_buildMenuArray();
    return $this->_appendCleanSqlReports($array);

I'd love to keep this rewrite as simple as humanly possible especially since this can be a common rewrite and people will likely have conflicts.

By the way, another approach I had thought of before was to do this client side in javascript prototype.  This would be nice b/c it would avoid rewrite conflicts and probably be a tiny bit better from a performance perspective.

But I know that would probably be a chunk of work, so we don't have to do it now.
