TwentyEleven showcase sidebar on wrong side

[WraithKenny]

TwentyEleven seems to be missing corrisponding .right-sidebar styles to adjust similarly to the sidebar template. (around line 135 in the css).

I'm not sure if this needs any of those crazy margin settings, so I'll leave that to Ian:

.right-sidebar.page-template-showcase-php #main .widget-area {
  float: right;
  margin: 0;
  width: 22.15%;

}
.right-sidebar.page-template-showcase-php section.recent-posts {
  float: left;
  margin: 0;
  width: 69%;
}

The showcase template is a specific design. It is not affected by the general layout settings.

That was also voiced by Ian in #18911.
