Usage

/** does account setup and login (and look up default folder if well-known account) from the given request.
 * request params are loginName<N>, password<N>, etc (see loginForm for details).
 * returns an object with {status: 0} if success, or {status: <non-zero>, errorMessage: '... '} if failure.
 * if success and account has a well-known sent mail folder, the returned object also has something like: 
 * {defaultFolder: '[Gmail]/Sent Mail', defaultFolderCount: 1033}
 * accounts on the login page are numbered 0 upwards. */
