Improve style of user popup

[feisley]

Quick update: In what appears to be a random case of caching, the popups suddenly changed to wrap around the profile picture and the labels are now more subtle.

Probably just something caught in the cache on upgrade.

I do still think we should consider dropping the label from the popup as it does widen it a bit, but otherwise it looks much better already :)

I combined this with the changes of #20. It is now combined with the possiblity to define presents views in the configuration and select them also for the hovers. By using <configuration ... hoverView="<viewId>" ...> and fix the whole style back to more confluence 5 normal style. This style could now also be selected in the marco.
