nav-tab class minor improvement

[alexvorn2]

in the dashboard panel .nav-tab should have

border-color: #DFDFDF #DFDFDF transparent;

not

border-color: #DFDFDF #DFDFDF #ffffff;

and

border-width: 1px 1px 1px;

not

border-width: 1px 1px 0px;

Because this makes the link with nav-tab class smaller with 1px in height.

This is how it needs to work to create the tabbed effect. See the credits page for an example.
