Support for Meteor 1.1

[alanning]

Just tried it with my production app and had a bit of trouble getting it to work since we still use Meteor 1.1.

Here's what I had to do to get it working:

• change the versions in package.js to Meteor 1.1 equivalents.
• use addFiles instead of addAssets.

Here's the git diff:

   api.addFiles(['client/index.js'], "client");

Should be able to support both without issue with some feature checking.

I'll put together a PR in a bit if you guys don't get to it first.
