add titles to abstract page, re organized abstract page, added mouseover...

... to results

Right now all list widgets are still using the same container template, should they be split?

I also made author names on the abstract page into links, as requested by Alberto
i have to 'protest' here :)

this shouldn't be inside the view, in fact, there already exist very suitable place for it - inside the controller, there is method processDocs() - modification can take place there
