Include Formula Change Detail in Model History

[bdeaton]

Currently the model history process only captures that a line item was edited but it doesn't specify if it was a formula change, applies to, etc... and it doesn't include what the formula is/was.

This came up recently in trying to research what had happened with a formula that had previously been updated and it's otherwise impossible to put together a good timeline of what happened when there is a lot of activity happening. External documentation is great, but it is prone to human error.
