Initial Addition of Sync Client/Engine for Diff Sync

This is more for a discussion at the moment.

This is the initial move of the code located here: https://github.com/aerogear/aerogear-sync-server/tree/master/js-client

If you look at the example in the above repo, you will notice that the user needs to interact with the patch/edits, etc...  methods.

I'm thinking we should have a more abstract API and try to make it a bit easier for them.

I'll be sending Updates, but look at the example to see how it might look since the aerogear.custom.js file has this code(sort of) included in it
