removing sidebar from single-post single-column template

[rclations]

fixes #1104

The single one column template states that it does not load any sidebars, however the included content-single.php partial does load a sidebar, which appears as an accidental mini-left-sidebar.

The parent ticket (#1104) suggested moving the sidebar to the right and making it wider, but then it would only be a clone of the two-column layout.

Another option would be to move the sidebar below the post content in the single column, and restyle so it appears naturally after the content.

I'm definitely open to thoughts & suggestions for how we'd like to tackle this. For now, I've removed the sidebar entirely, since that's what's already documented in the single-one-column.php file.

for reference, this is what the accidental sidebar looks like -

The docblock is wrong, unfortunately. I'll find an example of what this should look like, but it does need to be retained.

here's an example: http://wisconsinwatch.org/2016/09/wisconsin-must-do-more-to-protect-residents-from-lead-in-drinking-water-dnr-and-milwaukee-leaders-agree/

But here, oddly, it's on the right (where it always should have been). I'm not sure if something got screwed up when this was folded into the Largo parent theme and it's still correct in this child theme or what. But that's closer to how it's actually being used in practice by a few sites.

hm, on the other hand...maybe that's something they're just dropping into the body of the post directly. but that's generally what we'd be looking for here.

How about something like this?

this will also affect the two column layout (i think) so we may not want to do this...maybe

I think .normal is the class for our one-column layout, with .classic the two-column class, but I may be wrong here.

[aschweigert]

ah, ok that might be right (if not very clear)

[rclations]

yup, that's the case

Couple small things, otherwise the lgtm for now. In a perfect world we'd probably make this sidebar a little wider and either push it into the body of the content and/or out into the gutter. @Julia67 do you have any thoughts on this? I'm ok with punting for now if we don't want to mess with it. This doesn't get used too often anyway.
