Upgrade a zen cart module "AutoTweet" from 1.3 to 1.5

My project is very simple: i need that you upgrade from 1.3 to 1.5.x a zen cart module "AutoTweet" - Here is the module: [login to view URL] - and the relative component, the twitter app connection, see documentation at https://twitteroauth.com. So you test it and show me the result LIVE. Then you give me back the module updated to set-up in live shop. - - - - - - INFO: AutoTweet automatically updates your Twitter followers whenever you add a new product to your store (zencart). It will tweet your product's name as well as a shortened URL to the specific product's page without you having to do all the work. * Creator of the module: [login to view URL] * Library to support OAuth for Twitter's REST API from: [login to view URL] - [login to view URL] I have (and i cannot give to test) my Twitter API Key / API Secret + Access Token / Access Token Secret.
