New, Smaller User Format + New Request Handler + More Secure

###Introducing New JSOnTYPE Users:
Cenny.js users are no longer directories containing multiple files, but
are now contained within a single .json file.
The user's data, password, permissions, and token are all stored in
this file, instead of separate files as before.

To update your users to the new type (required), use the php script
inside the ```user_converter``` directory.

###Introducing A New Smart Request Handler:
Requests are now combined and sent together when possible.

Example:

```javascript
myServer.update({property:12});
myServer.get(function(d){console.log(d)});
myServer.update({app:true});
```

**All three requests would automatically be sent as a single request.**
