[Feature Proposal] Utility to set border-spacing: 0

[brandonpittman]

Been doing some table styling and I realized that border-radius will only work if you separate borders on tables. Unfortunately, in order to make all the other borders go flush against each other, you then need to set border-spacing: 0; to get rid of the gap. I'd like to propose one of the following:

1. border-compact or border-spacing-none class that just sets border-spacing: 0
2. Go full on nuts and incorporate the theme's spacing key to create a full suite of border-spacing utilities

#2 is probably overkill. I can imagine someone else has had an issue like this with tables. I wonder if anyone ever actually wants the separated look on a table anyway. Maybe it's worth setting border-spacing: 0 as a base style in the base.css file.

Thoughts?
