Add support for object paths in target (+ 2 new object functions)

[limiter121]

Added support for using object paths (like myobj.a.b.c) as target.

Example:

<input target="person.address.city" placeholder="Where is Kevin from?">
<p var="person.address.city"></p>

// Create a var for Display.JS. You don't have to add the $ var, you can change the name.
var $ = new DisplayJS(window);
// Create an object 'person' who's name is 'Kevin', and he lives in New York.
var person = {name: 'Kevin', address: {city:'New-York'}};
// Rendering the DOM
$.var();
$.target();

Also added 2 new functions getAtPath, setAtPath for use with objects and paths.

Example:

var $ = new DisplayJS(window);
var person = {name: 'Kevin', address: {city:'New-York'}};

// Get value at path
console.log($.getAtPath(person, 'address.city')) // Output: New-York

// Set value at path
$.setAtPath(person, 'address.city', 'San-Francisco')
console.log($.getAtPath(person, 'address.city')) // Output: San-Francisco

Thank you very much for that. I’m trying to fix Travis build before merging. Nice 👍 work.

I’ll try to create a release as soon as possible. But because DisplayJS isn’t my main project right now, I can’t guarantee that I’ll be able to release it this week.

If you’re interested in DisplayJS, you should checkout my new framework that is still in development: https://protype.js.org
