Restorative virtues vigor share

[Kuya.6495]

Summary: change restorative virtues so the vigor from flowing resolve is shared with allies and not just yourself.

Justification: currently heal alac willbender is in a relatively good spot but it does lack one important boon to share: vigor. Now I know anet wants supports to have trade offs but by putting vigor share in restorative virtues, a support willbender has to choose between might share from holy reckoning or vigor share via restorative virtues and therefore creating a tradeoff. 

That or make a relic that gives allies vigor on shadowsteps or something.
