(Editorial) Add border lines (or use different colors) to table rows

[iherman]

I find the specification of the properties in §2.1 BitstringStatusListEntry very difficult to read, because it is not clear where, for example, the definition in the right column for id ends and type begins. Please use some visual clues (borders, background color, etc) to overcome this.

I have checked the html source, and I must admit I am a bit lost. The source uses the same class="simple" attribute for tables as, say, the VC JSON Schema document does, but the rendering is different. At first glance, I did not see any difference in the respec setup or the included files. I cannot explain what I see, but the editors may know this...

Older versions of ReSpec had a "simple" table class. That has been removed, for whatever reason. I added the missing CSS classes back in for simple tables to make it easier to read.

I have fixed this in commit 47e1900. Closing.
