Cannot compare copied objects accurately

[Griffinz]

With the changes to copy() from: #1875

hashkeys are no longer copied from the source. However when comparing two objects with angular.equals(o1,o2), hashkeys are still taken in to account.

Can hashkeys be ignored by equals()? Since hashkeys are omitted from copy(), the same rule should be applied to equals().

Expected behavior: angular.equals(foo, copy(foo)) === true;

@Griffinz: angular.equals() ignores all properties beginning with $, and all properties whose values are functions, when both arguments are objects. Therefore, I'm not quite sure what you're getting at, can you post a reproduction demonstrating your problem, or write a failing test? I think this might be a problem if they are array-like objects

...Nope, I'm wrong, it seems to work just fine with arrays.

Because the issue tracker is so packed lately, and as far as I can tell this is invalid, I think I need to close this. But if you can demonstrate a situation where this doesn't work as expected, please open another issue with a detailed reproduction. Thanks~~
