Getting rid of non-forwards-compatible INSERT statements

[ashalkhakov]

First off, thank you for a great tool.

I have this issue at work where we have a moderately sized T-SQL codebase that uses the statements of the form

INSERT INTO <table>
  VALUES (<values>)

I would like to refactor all of such cases that we have, and disallow them in the future. This tool fits the bill. I've created a PR #268 with a proposed implementation of such a rule and would like your feedback.

This would be very useful to have as a rule! +1
