Errors : updated version

[tchak]

In this version, we handle validation errors and server errors.
Some ground work is done in order to prepare client side validation support.

For the error handeling part tests are much more complete.

Adapter part is a work in progress (need tests)

love to see this in ember data

Wow, I hadn't completely understood your implementation until I tried to achieve something like that myself. It's great, I also found out that transactions don't try to re-commit records when they're invalid.

I really hope this gets merged into ember-data, it's a must-have.

@tchak What's the status of this? I see it doesn't merge cleanly.

I talked with @tomdale about it and he did not like it to much I think...
I can rework this but I would like a proper review in order to know what exactly should I change.

One thing that was proposed is to make errors object use Enumerable interface. I will look in to it.
Another question is, should we handle server validation errors, client validation errors and plain server errors on the same interface?

Realize there's probably more pressing 1.0 Beta work to be done, but I'm real curious about the discussion here. I was just trying out using your errors implementation @tchak with modifications to implement Enumerable . Would love to be of help here however possible.

Closing in favor of #360
