// this file contains main Myspace Connect logic

// Workflow
// *** read http://wiki.developers.myspace.com/index.php/Connect/Authentication_and_Authorization
// ------------------------------------------------------------
// 1. Temporary user, on login dialog:
//   a) show "connect with myspace" button
//      when user clicks it, it performs scenario 1,2 or 3 from ***
//      after authorized user comes back from myspace:
//      test if user is already associated with some of our accounts:
//      * if yes, perform auto-login
//      * if not, present special registration form
//        - do not provide password fields
//        - pre-fill form fields with data from Myspace
//        -> when user creates account this way, make it associated with Myspace user
//        -> if user enters exising email, present special UI for password and let him log in and associate automatically (Peter)
//      in both cases transfer all temporary data to real account (if any)
// 
// 2. Logged user, on "My Account" page:
//    a) if account is already connected with myspace => show "reconnect" and "disconnect" actions
//    b) if account is not connected => show "connect with myspace" button
//       when user clicks it, it performs scenario 1,2 or 3 from ***
//       after authorized user comes back from myspace:
//       * assign this myspace user to this account
//    
//    reconnect action works similar to b) but first forces logout from myspace (it is just safer to ask user again for his myspace credentials, than explaining it in the text)
//    disconnect action simply removes myspace user association from our account
//
// TODO: account.php has no support for loading indicator and is throwing alerts when something goes wrong
// TOOD: when disconnecting from myspace check if user has non-empty password, so he is safely able to log back using email/password
