Error handling

[kohltastrophe]

In cleverbot.js you have an issue on line 58 where the eval will error without catching it, halting the program.

This can be fixed by changing line 58 from: eval("responseBody = " + body) to: try {eval("responseBody = " + body)} catch(e) {console.log(e)}

AND changing line 60-61 from:

responseBody.message = responseBody.output;
this.state = responseBody.cs;

to:

try {
responseBody.message = responseBody.output;
this.state = responseBody.cs;
} catch(e) {console.log(e)}

Thanks for the great package otherwise!

I added an errorCallback argument to the write function. I don't want to make assumptions about how users want to handle errors. If an error occurs, the callback is called and the write function just returns without continuing. I hope that is enough.

Thanks!

Even better than my temporary fix, keep up the good work!
