added support for WHERE `column` IN ?

Also patched the debug console display to reflect changes in 8972c81

Been using it for a week in production with no issues, its helped streamline a lot of my queries that I was manually writing for this. It doesn't implement any type of check to make sure the operator in front of it is `IN` but, if its not it fails gracefully. The error message from sql if the operator is `=` is `Operand should contain 1 column(s)` which is a little ambiguous, but if you're using this functionality chances are you would understand the problem. 

It has the added benefit of not causing an exception if you accidentally provide the replacement array with an array, since previously the code didn't check for such a thing.

If you decide not to commit this I'll send you a pull request for just the debug console display (or you can cherry pick it)
