Long versions cause linewrap in search results

See:

I think we should add the CSS property that will make them show as v0.1.0-as... (with the dots), and a hover component that shows the full version.

Alternatively, we could also implement it such that we get the crate name (in full) and then the version on the next line.

with regard to #38 i dont think yet another line makes sense. Besides i think this does not happen for most crates and mostly onmobile. I d just go with the hover solution - maybe give the crate name more max space than version (does the rc really matter for the overview tile? - version selection is on the next page anyway)
