Exotherm - Hardcoded responses

After some testing today I determined that Exotherm's new ability to record the moves that led to unexpected certain doom is not working as well as I hoped. It seems like the doom is detected a half-move too late in the very common 1. Nf3 trap. It looks like I would need something more sophisticated for Exotherm to make any progress in the general case. As a temporary measure, I added a configuration section for "hardcoded" responses to recognized positions. Currently I'm only manually configuring 1. ...f6 as the response to the knight threat, but once Exotherm is deployed I would monitor for other repeatable traps.
