$ prefixed properties sended from the server are filtered in the ngResource ver >= 1.2.6

[atomrc]

Some of my resources, retrieved from the server, has some '$' prefixed properties. With angular >= 1.2.6 those properties are filtered when the resource is requested against the server (I think it might occurs on the shallowClearAndCopy function).

I know using '$' prefixed properties is not a good idea as they have a specific signification for angular, but what can I do when the server is using and sending those properties ?
Is there a real interest in filtering those properties when the resource is created ?

[atomrc]

I did a PR to fix this : #5666
