Make Dashboard tabs look consistent with other subs

This is my first go with github, please tell me if I can do anything better.

As per the description on my commit, it requires changes to the custom stylesheet for /r/dashboard, however only honestbleeps has access to that so I'll explain which CSS needs to be deleted below. It only affects the appearance of the main tabs (.tabmenu).

**To be removed:** (it's compressed because I can't access the raw css)

    ul.tabmenu{display:none} .redditname a{margin-right:5px;padding-left:5px;padding-right:5px;cursor:pointer;border:1px solid #eeeeee;border-bottom:none;background-color:#333;color:#fff;opacity:0.6;font-size:small;text-transform:lowercase}.redditname a:hover{opacity:1;text-decoration:none}.redditname a.active{opacity:1;color:#000000;background-color:#ffffff;border-top:1px solid #5F99CF;border-right:1px solid #5F99CF;border-left:1px solid #5F99CF;border-bottom:1px solid #ffffff}
