Working example of friends list on the user

[schickm]

So, after much mucking around I figured out how to do it.

What needed to happen is that you needed to add the friendslist to the user when the account get's created. To do so you have to take advantage of Accounts.onCreateUser:

http://docs.meteor.com/#/full/accounts_oncreateuser

That is a hook that get's run on the server. You might think the solution would be to add it to the profile, but one gotcha is that only changes made to the top level of an object are sent over the wire from the server to the client. So if you change something in the user's profile on the server, that change won't get sent back to the client.

So I ended up adding a 'friendslist' property directly onto the user. This required me also to create an allow method so it can be updated, and also create a publication/subscription of that same property.

I've annotated the commits with comments as well
