Tpl support

# Description:
Added support for tpl localization.

Notes:
Only implemented for Sencha Touch! Not Ext.
Only tested on ST 2.2.1

This was implemented in the Component override, so it should work with every component child object.

# Usage:

1. Create the component with the `data` and `locales.tpl` like so:

```javascript
var welcomePanel = {
	xtype: "panel",
	data: {
		name: VSBabyMobile.app.vsbUser.get("UserName")
	},
	locales: {
		tpl: "home_screen.hello"
	}
};
```
or: 
```javascript
var welcomePanel = {
	xtype: "panel",
	data: {
		name: VSBabyMobile.app.vsbUser.get("UserName")
	},
	locales: {
		tpl: {
			defaultTpl: "Hello {name} and welcome!",
			key: "home_screen.hello"
		}
	}
};
```

2. The `locales/{locale}.json` file will have the template:

```javascript
"home_screen": {
	"hello":"Olá {name} e bem vindo!",
}
```
