[ticket/12327] Changing poll result-bars width from absolute to relative

Currently, the bars indicating the results of a poll represent the width as an absolute percentage. The result is that when there are multiple poll options that all get about the same amount of votes, the result bars tend to get really short, and not very descriptive. I suggest making the "winning" poll bar 100%, and all other widths relative to it. This is much more esthetically pleasing if you ask me, because it really gives users something to look at. Additionally, I add a "winner" class to the winning poll bar, so it's easier to style it in a special way.
