Support Theme: Get rid of empty space in home page footer

[SergeyBiryukov]

[5927] and [5946] temporarily removed topic tag clouds from the Support Theme due to performance issues caused by ​[WP41377].

In the ​latest #forums meeting, the consensus was that topic tag clouds don't really add any value to the forums and should be removed permanently.

This leaves a large empty space in the home page footer, see the screenshot. We could fix that by moving the "Helpful Links" section higher, next to "Themes and Plugins".

3152.diff is an approach to get the Helpful Links div next to the Themes and Plugins and also sort it for the responsive theme as well.

Note: the CSS changes where made into style.css I'm not sure if they had to be done in the SCSS files instead. I was actually previewing all the changes with my chrome console ( no idea how to enable the support front-page on the meta environment :D )

I think lining up the "Themes and Plugins" with the "Helpful links" is a good decision. My only suggestion is to put both of them below the line of links "All topics | Topics with no replies | Unresolved topics". That line of links could be a divider between them both.

From the discussion of the last meeting in #meta: this will be changed as soon as HelpHub lands since it will change the design of the whole page. No need to update it individually now.
