Add http.onError function to handle all errors

if using a custom RequestEngine.ts you can define a method called onError() to handle all thrown errors in any http request.

See How To Extend Request Engine

class MyRequestEngine extends $.extendedRequestEngine() {

     onError(error, formattedError){
         // Respond how ever you wish
         this.send({message: error.message. formattedError});
     } 

}

Xpresser checks if this function exists and then calls it.

Upgraded Object-collection

Updated Xpresser to version 0.26.0
This version includes minor Typescript Related breaking changes regarding the new typed object-collection

Since object-collection is widely used in xpresser you may now need to declare types when accessing object-collection instances.

For example

// This may throw a type error
const name = http.$body.get("name");

// Proper way.
const name: string = http.$body.get("name");

// OR
// Proper way.
const name = http.$body.get<string>("name");
