Default theme should use word-wrap in tables

[zleonov]

Long field names overflow the width of the table columns resulting in erroneous output (picture attached). I use the dark theme (https://github.com/anvilco/spectaql-dark-theme) which is based on the default theme. This is true for both themes.

I added the following custom styling to custom.scss: table { word-wrap: break-word }. That did the trick. It's important to use the "break-word" property since field names don't contain spaces. But this should probably be added to the default theme, and probably there is a better way to do it.
