Sending another breaking change, this seemed like an oversight. I renamed .table-inverse, .thead-inverse, .thead-default to .table-dark, .thead-dark, .thead-light. I also changed the variables $table-inverse-* to $table-dark-*.
The last commit fixes a bug where .thead-inverse and .thead-default doesn't apply the proper variant border color, also made the selector more specific so that it will win over the parent .table class e.g. using .table-inverse with .thead-default.
