DDBNEXT-844: made some changes in summaryMainWrapper and
thumbnailWrapper (span7->span6 and span2->span3 respectively). Put new
style-info into results.css and linked it via new div-tag "icons-right"
with thumbnailWrapper.gsp view. Now the layout of the result page looks
as seen on the pic in Jira (search_results_v2.png).

implemented task 844 (desktop view) for 3 buttons on the right-hand side
