[WIP] Strip restangular methods from entries

[fzaninotto]

Angular adds its own method to every entity fetched. As they are not namespaced, this has side effects.

I removed them, but I'm not sure we don't use them. @manuquentin, any insight?

Fixes #273

[manuquentin]

We can maybe put this in the view.mapEntry method ?

[manuquentin]

Restangular methods aren't used on the object himself, we can remove them

[fzaninotto]

As a matter of fact, my patch doesn't solve #273, because properties named like Restangular methods (like "head") are added then removed, so there is no way to read them. We need a way to prevent Restangular from decorating them in the first place.

[fzaninotto]

We can't prevent Restangular from decorating, but we can get the original entity by adding a listener (see mgonto/restangular#100 (comment)). Back to WIP.

I've fixed the bug, but there are two drawbacks:

• This breaks all tests using Restangular (long and cumbersome to fix)
• This slows down the app, as we have to clone all entries in order

So this needs more work.
