variation statistics on mouseover

[gnos]

When the mouse hovers over one of the variations (including the starting move of the joseki), a small tooltip box should appear showing the popularity of the move among josekipedia users, and also the popularity in progames cited from a reliable source.

this is a nice idea, thanks.

One might also consider including the first so many characters of the description. In this case [src] and [path] markup should probably be stripped out and position markup displayed as coördinates.
