Title: SwiftJSON update feature implemented

Just tried to achieve modification feature especially for https://github.com/SwiftyJSON/SwiftyJSON/issues/60
Maybe api should be refined, but now it works like this:
```
let json = JSON(object: [["user":["name":"Anton"]],2,3])
println("Before: \(json)")

let json2 =
json.updated(0) {
$0.updated("user") {
$0.updated("name") {
JSON(object: $0.stringValue + " Bukov")
}
}
}
println("After: \(json2)")
```
Output:
```
Before: [{
user = {
name = Anton;
};
}, 2, 3]
```
```
After: [{
user = {
name = Anton Bukov;
};
}, 2, 3]
```
