Horizontal scrollbar for images

[marc-farre]

Upload a wide picture in a post, wikipage or other Richtext:

The image has width="100%" wich is correct, but also margin: 0 5px; which creates an horizontal scrollbar:

[data-ui-richtext] img:not(.center-block) {
    max-width: 100%;
    margin: 0 5px;
}

@yurabakhtin Does it still look good now without margin or Is there no difference? Can you please post a screenshot?
Maybe you should use a padding instead of a margin?

[yurabakhtin]

@luke- It looks like without margin, if we need the space then yes we should use a padding, should I use padding?

@yurabakhtin Thanks for the screenshots. The variant without margin is really the best. I'll merge the PR.
