[Not Dawntrain] Fix incorrect return type

[MidoriKami]

Addon Lifecycle originally tried to use OnRefresh as a void return, but that caused a bunch of corruption errors, we discovered this issue and fixed it using our own delegate. Since then ClientStructs has added these functions, but they were added with the wrong return type.

char Component::GUI::AtkUnitBase_OnRefresh()
{
  return 1;
}

char __fastcall Component::GUI::AtkUnitManager_RefreshAddon(
        __int64 a1,
        Component::GUI::AtkUnitBase *a2,
        unsigned int a3,
        Component::GUI::AtkValue *a4)
{
  if ( !a2 )
    return 0;
  Component::GUI::AtkUnitBase_SetAtkValues(a2, a3, a4);
  return (a2->union.vtable->OnRefresh)(a2, a3, a2->AtkValues);
}
