Small fixes for RES upcoming changes, zero impact otherwise

The current source build adds a "multi-count" counter (counts how many multi's the subreddit is in) as a span inside the subscriber button span. So updating the .subButtons span:not(.subscribe-button) to .subButtons > span:not(.subscribe-button) should address any future issues of nested spans becoming buttons while also just hiding the "multi-count" all together since it's fairly useless anyways.

I'm not comfortable completely hiding a feature users may be using. I know it's screwing up the sidebar (it is for most subreddits) and RES doesn't have a way to disable it, but I'd like to wait a bit longer.

Yeah, if it does get pushed though, there isn't gonna be a decent way to keep all those buttons on the same line though without shrinking the text further and killing the symmetry. Might just wanna make it 2 lines at that point. What bothers me is it doesn't actually add anything meaningful. Hovering over the sub button tells you what multi's it's in. All this does is provide a counter, as if you need that every time you view the subreddit.
