RedditSearch - update design

Fix for issue #706 - it's not complete, but I want to share the progress anyway, so you can see if you like the work so far, or if I must change something!

I still have to make the subtitle all in lowercase, but I can't find where in the code the first letter of each word is capitalized; another thing I haven't done yet is putting the arrow pointing upwards on the left of the score: should I use an asset or is it representable using a font character?

Anyway, this is how the instant answer looks after my changes:

I don't like the space between title and subtitle when the first is short:

Maybe I should position the subtitle differently, in order to make it appear always after the same amount of space? But then the subtitles in the different boxes wouldn't be horizontally aligned...
Ok! So should I do that for months and days too?
