[MonoDevelop] Some changes to ambiences

I've thousands of methods that are:

VisitSomething (Something something, object data)
{
..
	GetString (something.SomeObject, data)
..
	IsValidSomething (something, data)
}

etc. The visitors are operating on objects. This method prevents that
I've to upcast the data objects in each visit method as ambience
implementor.
