[website] show one-line project description in list of recent updates

[uvtc]

On the recent updates page, I think there should be a "Description" column there as well (right after project name), the content of which would be the project's one-line description (already present at the top of each project's specific lib.haxe.org page).

When browsing the list of recently-updated projects, I don't know what most of them are. Though it's nice to see a column for "Changes", that info doesn't make sense if I don't know what the project is. Currently I have to open each link so I can see its description line at the top.
