tasks #6956 Mustachify results page

Heavy refactoring on going, the results are not mustachified yet

Pagination was removed but will be back soon.

Search on "all_trackers" and "ajax" were removed because we (bdauton & grep
& I) didn't find any evidences it was still used.

"tracker" search is slightly modified, the results are now displayed within
search page instead of a "fake" tracker v3 page
