Small escort tweak

[SageAcrin]

An interesting thought I had to make Escorts a little more interesting; Allow them to buff categories they teach by 0.1 Category Rating, if you know the category.

This could be capped off at 1.4/1.5, but I don't think that's necessary with the new infinite scaling; If you're getting tons of a single escort, it's nice to have them be useful, and in general stacking a lot of a single escort is essentially being unlucky, not lucky, right now.

Sounds interesting. Nothing that would break the game yet should make escorts marginally more useful.

I second this.

It would allow you to take a learned ability (from an escort) and bump it up to a normal level. I think this is a good idea.
