HealAura only certain classes/subclasses

[Bonjemus]

Is your feature request related to a problem? Please describe.
I would like to create a subclasses that can heal only one subclass/class with his heal aura.

Describe the solution you'd like
A clear and concise description of what you want to happen.
Add a new optional boolean option for HealAuraAbility "HealAuraOnlyCertainClasses".
Add a new string option called "HealAuraOnly" that is required when "HealAuraOnlyCertainClasses" is set to true in which you would have to put the classes/subclasses names. It would look like this :

string_options:
HealAuraOnly: ClassD, ChaosInsurgency

boolean_options:
HealAuraOnlyCertainClasses: true

Hopefully I was clear enough.
