Hg 78 horizontal table scrolling

**DO NOT MERGE**

Check out the Bestiarum page on the Halo wikia to see it in action near the bottom of the article content. Also check out John-117 in Halo to note that this update will wrap _all_ tables in borders and make them scrollable if they are too wide. Not sure what we're going for with something like the info table at the top of John-117.

update: @kenkouot @hakubo I've taken your comments into account, it should be ready for merging unless you have anything else
