Turn active tabs color to #DDDDDD

Set background color to grey and avoid white space between tabs and tabcont class

Set tabcont to a slightly darker grey so that it stands out even on brighter monitors.

Do not use /, use relative directory form css

Make the new tabs themable

Add the openvpn users graph, add the colors to all the themes colors include. Add vpn tab
