Add pop-up dialog for authentication to SocialConnect extension

[anatolykazantsev]

We need to modify this extension to show a pop-up dialog when a user wants to register/login using social networks.

Overall design

1. Show a pop-up dialog to register or log-in action when a user clicks on Log in or on Register links. 2. The dialog should contain a form with email and password and buttons for social networks.
2. Split the dialog into two parts: left - log in/register forms, right for social buttons.

See following images for a layout example:

Templates

Re-use existing templates as much as possible, so that the pop-up dialog has the same design as the theme in use.

Use default Magento templates for registration (customer/form/register.phtml) and log in (customer/form/login.phtml) actions
Add support for persistent templates (persistent/customer/form/login.phtml and persistent/customer/form/register.phtml).

The dialog should contain both register and log in actions to let the user switch between them using only CSS without additional HTTP requests.

Social buttons part should be re-used from SocialConnect as is. See app/design/frontend/base/default/layout/inchoo_socialconnect.xml and app/design/frontend/base/default/template/inchoo/socialconnect/customer/form/register.phtml files.

Javascript

Pop-up dialog should work with the new RWD-based theme, so the extension should use jQuery.

Code and repository

New code must follow the project's style:

• 1 indent = 4 spaces
• Line ending = LF (unix)

Create a fork of the project under your account and use a separate branch on top
of the project's develop branch. Give it a self-descriptive name, e.g. popup-auth.

Split changes into logically separated commits. Each commit should have a short
title and more detailed comment.

Use the same license text as in other files in this project: acknowledge Inchicoo, change the copyright to mVentory Ltd. and author to your name.
