Tpl support

[tralves]

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:

var welcomePanel = {
    xtype: "panel",
    data: {
        name: VSBabyMobile.app.vsbUser.get("UserName")
    },
    locales: {
        tpl: "home_screen.hello"
    }
};

or:

var welcomePanel = {
    xtype: "panel",
    data: {
        name: VSBabyMobile.app.vsbUser.get("UserName")
    },
    locales: {
        tpl: {
            defaultTpl: "Hello {name} and welcome!",
            key: "home_screen.hello"
        }
    }
};

1. The locales/{locale}.json file will have the template:

"home_screen": {
    "hello":"Olá {name} e bem vindo!",
}

Looks pretty good! I'm gonna find some time to test this with ST2 and Ext JS4 before I merge it but looks like it should work for both. Well, maybe not the getters but we shall see :)
