A few changes for 3.9.1

Styles were not playing well with 3.9 on the widgets page. I changed
them to be borders and moved them up a level in the html to wrap the
whole widget box. See comments in the js for details

Added a settings page shortcut from the plugins.php page
Full colour change

Changing the full border color to dark blue
