Make Marius' Hunter's Sense a MC ability

[Helz]

I think it was a great decision to make spell pods an alternative to Yatzli's 'dispel illusions' ability. But Marius' "Hunter's Sense" feels even more mandatory to me. Revealing hidden items is nice, but the real value is quickly verifying that there's nothing around. It saved me so much time, that I ended up keeping Marius in my party for the entire game, even when I would have preferred to use a different companion.

It would be awesome if you could make "Hunter's Sense" an MC ability that Marius can teach you.
