EJSON support

[emgee3]

I pushed a new branch that adds EJSON support. I included the EJSON smart package files in the ddp client as a temporary measure, until there's an EJSON npm package. I spoke with sixolet on IRC and it's on her list of things to do.

Feel free to check it out. It could use a bit more testing, but generally speaking it works.

@emgee3 - do you need this urgently? If not, I say we should wait for @sixolet to upload EJSON somewhere before releasing this.

[emgee3]

No, I don't need it at all. Mostly just to have it around if someone else needs it.

[tmeasday]

@emgee3 - did you get any further with @sixolet here? I can ping her again about it if you'd like.

[emgee3]

@tmeasday @sarfata I updated the ddp-pre1-with-ejson branch now that we have the meteor-ejson npm module. So if you would take a look, that would be good.

It works with the built in EJSON types, though I don't know if we need to add anything else to support custom EJSON types.

@emgee3 cool! good stuff.

I'm on vacation right now, but if either of you want to publish a new version of the package let me know your npm username and I'll give you access on npmjs.org

Following up on this, I've filed this PR sixolet/ejson#2 which handles meteor/meteor#1001

Probably should add a few tests. The question I have is should we test the DDP client connecting to an actual Meteor server, or would mocking the components suffice? I don't actually write tests nearly as often as I should. Any input @sarfata or @tmeasday ?

Hey @emgee3. You could take a look at Meteorite's atmosphere acceptance tests.

We use Mocha to connect to a local atmosphere running on port 3333 and inspect the results on the command-line. I'm not sure if they pass right now due to conflicts in the way that Meteorite + 0.6 Meteor work but it could give you some ideas for acceptance tests.
