Adding my personnalised Zend GData Library

Using self::$_useObjectMapping in App.php as a static attribute of
Zend_Gdata_App class
To correct an issue :
Declaration of Zend_Gdata::import() should be compatible with that of
Zend_Gdata_App::import() Zend/Gdata.php:45.
Some comments and code correction
Updating the layout and adding a new welcome page
Editing the .htaccess to add Zend to the include_path
Updating the schema create sql file
Updating the controller

With a primary Facebook API integration
And a primary Youtube Gdata API integration
Updating the channel view
