angular-ui github website: dropdown menu and previous versions lisst

[mg1075]

As someone who frequents the angular-ui bootstrap documentation website, and has to look at some of the older docs (thank you for keeping those around!), please note that it is difficult to select older items from the "previous docs" menu.

Perhaps add custom css as follows so the menu list can be usable again.

.navbar-nav>li>.dropdown-menu {
    ....
    overflow-y: auto;
    max-height: 400px;
}

Feel free to file a PR - this would need two PRs if you do embark on this, one to the gh-pages branch modifying all of the CSS files for the docs apps, and another for modifying the JS template in the docs app here: https://github.com/angular-ui/bootstrap/blob/master/misc/demo/assets/demo.css
