Allow overridden properties that inherit attributes

[magneticflux-]

Previously, the property in the base class and the property in the subclass would both be returned, causing us to complain about duplicate arguments/options that are actually the same.

Closes #555

I think this handles all cases of property overriding while still correctly flagging property hiding/similar-looking private properties, but I'm new to C# so I might have missed an edge case!

@natemcmaster Just a friendly reminder!

If you'd like, I could also try adding a regression test for this specific case of attribute inheritance so it doesn't get inadvertently removed again.

Hey, thanks for your patience and the reminder. I had been taking a break from open source. I think this looks like a legitimate bug that needs fixing. Adding some tests to show the bug (and that this change fixes the bug) would be good.

I know it's been almost year since you opened this, so sorry for the long delay .
