[Bf-modeling] proper behavior for knife cut, midpoint snap mode

[metalliandy]

Technically I would expect the mid point snap to snap to all 
intermediate points but I can also see the usefulness of the other 
option where the it only snaps to the last edge at the midpoint.

I wouldn't personally like to endorse the work around suggested as it 
would be a laborious fix that only gets compounded as the face count 
increases. It would be far faster to workaround the no midpoint snapping 
by subdividing the starting and target edges and then cut a linear line 
between the newly created verts.

If we really don't want to add another hotkey (though perhaps something 
like double CTRL press would work?) I would suggest keeping the snapping 
to intermediate points option as it's much slower to workaround.

Perhaps we could add a new addition to the constrain angle where the 
tool gives an option to snap to midpoints instead of adding a new hotkey?

Cheers,

-Andy
