Actually 1.11.6 and later for ellipse crap
Don't define unit type ellipses for Anya's unit types

This solves all the bullshit surrounding her ellipse allergy throughout
AtS E2 and E3. The new 1.11.6+ ellipse semantics apparently involve
allowing the unit type ellipse overruling singular unit ellipses (unless
they are set by [modifications] maybe? haven't checked).

We still do want a misc/ellipse ellipse for her L1 unit type on Wesnoth
1.11.5 and earlier, though, so that's #ifver'd.
Don't force the standard ellipse on Allyna's L1 unit type on 1.11.6+
E3S8B: Replace manual IS_HERO override with NO_OVERLAYS_NO_ELLIPSE
