Feature Request: Assisted `>debugmods` (Fred command for binary search)

[Th3Fanbus]

Having to manually enable/disable mods when debugging is extremely tedious, error-prone and may even result in RSI (Repetitive Strain Injury) for a big enough mod list. It would be nice to have SMM assist in the process, similar to how git bisect automatically checks out the commits to test and allows the user to mark them as good/bad. It would also be nice to save a log detailing what mods were present in each test, in case the issue is more complex.
