Prodigious Two Weapon Fighting not considering the Giant Weapon Wielder feat from Titan Fighter subclass

[aetnaeus]

As title, the PTWF feat does not consider 2H weapond wielded in one hand as one handed weapon, as the GWW feat states they are, thus not rendering them light and not reducing the TWF penaltly accordingly.

I created a pull request for a tentative fix on the issue, can't test locally 'cause the project itself won't build due to many protected methods being overridden as public.
