Improve no result page

I've done mostly on No result and a little on result page. Changes are:
 - Add link to Task::Kensho on No result page ( #616)

 - A (small) spelling suggestion when search with incorrect Perl module e.g. DBIx:Class, DBIx:::Class:ResultSet (from Oalders comment on #616)

*Hopefully we can add more suggestion keywords using suggester from ES but this could happen after we upgrade ES to later version (0.90+) 
 - Redirect to the module if there's only one result from search (#777)
 - Make font size larger on result page (#515)

First intention was trying to make font size larger on no result page but as a result of the changes I've made. I removed the text ( 0 results (0.xxx seconds) ) from no result page but this change still apply to result page. Which I think it nicer. (What do you think ? :D)

I made these changes  based on my opinion, so you might not like it or have better idea. Any comments and suggestions are really welcome if you could give me to make MetaCPAN be brighter and better :)
