Hide reply, quote, and PM buttons until hover/select

[dovej]

With the new, larger action buttons (reply, quote, and PM), we should hide these by default and have them appear when you hover over a message or select a message. On mobile, this should be accomplished by tapping the message probably.

The thing about hiding them until you hover them on the desktop is this: suppose you've selected message A, and you're hovering over message B. Hitting r will reply to A, even though B is the one with the visible reply icon.

Meh. I think the pros outweigh the cons here. Unless there's a better solution I can't think of. Right now I think the big buttons on every message are an eyesore.

I agree they are an eyesore. Since this looks like it was intended to make mobile button clicking easier, why don't we just make them smaller on Desktop?

[dovej]

That's an option. I suppose they looked fine being on every message when they were smaller?

If you're going to be adjusting UI based on input capabilities, these are the media queries to look into:

The question remains whether we really want them on every message on mobile though, for space reasons. (And subsequently whether or not we want to be consistent on desktop.)

I don't think pointer:coarse is supported that widely yet. We need to use Modernizr and detect the touch/no-touch 'features'.

(Detecting the screen size is explicitly not what we want here because tablets.)
