Adding support for localization in XML files also

Now that we can use L() in XML files, we must be able to extract it also.
Delete method shouldn't reset model's id

Model's ID should not be deleted (reseted) in the adapter. The problem is that after the `Sync` is done Backbone will trigger destroy which will execute a method called `_onModelEvent` -> `remove` ,but model doesn't have an id anymore ,so it won't be deleted from a collection - set (`_byId` /  `_byCid`). If you try to add a new model to the collection with the same ID, backbone will not allow you to do that because the ID already exists in the set.

Example:

test.js (model)
~~~~javascript
exports.definition = {
	config: {
		columns: {
		    "id": "INTEGER PRIMARY KEY",
		    "whatever": "TEXT"
		},
		adapter: {
			idAttribute: "id",
			type: "sql",
			collection_name: "test"
		}
	}
};
~~~~

index.js (controller)
~~~javascript
var testCollection = Alloy.createCollection("test");

var model = Alloy.createModel("test", {
	"whatever": "..."
});

model.save();

testCollection.add(model);

console.log("Models in `testCollection`: " + testCollection.length + ", Model ID: " + model.id);

model.destroy();

console.log("Models in `testCollection`: " + testCollection.length + ", Model ID: " + model.id);


var newModel = Alloy.createModel("test", {
	"whatever": "---"
});

newModel.save();
testCollection.add(newModel); // Won't add this model

console.log("Models in `testCollection`: " + testCollection.length + ", Model ID: " + newModel.id);
