Collapsable Navbar needs a better button

[jasonsperske]

Here is what I ended up settling on, but I don't know if this is in keeping with the spirit of DOS UI so I wanted to see if anyone had any better ideas before I try and submit a patch:

<div class="navbar-header">
  <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
    <span class="sr-only">Toggle navigation</span>
    ≡
  </button>
  <a class="navbar-brand" href="#">Project Name</a>
</div>

Also I added this CSS to eliminate the border:

.navbar-inverse .navbar-toggle {
  border: 0 none;
}

just submit it. I'll look into it. Thanks!!! :)
