Ability to set sidebar classnames in 5.0

[beckyaiken]

In the 4.1 appearance tab, there are fields where you can set the classname for grid columns when there is a sidebar.

These fields aren't there in 5.0, and I think it would be nice to be able to switch it to a 3/4 + 1/4 column grid instead of 2/3 + 1/3.

Also, I just noticed that the "disable drilldown menu" isn't there anymore either — not sure if that will impact sites as well.

It was my dream to just do away with these but I'll add them back.

The "drilldown menus" (menus that change as you go into a site, following the breadcrumbs) really isn't desirable any more with the breadcrumb system going away, and ultimately was ruled a bad idea anyway. The alternative is using Groups so that the menu AND the site title can be changed rather than just the menu.
