Release limitation of phone number

[channy]

In S3's static web app, ng-pattern="/^[1-9][0-9]{9}$/" in signup.html and Value : '+1' + $scope.user.phone in signup.js limit to add phone number of international users. It effects to Twillo Lab that users have to change phone number manually in DynamoDB for validation of their real number. Please release validation option of +1 and 10 digital number.

+1. This breaks the workshop for non-US people.

+1 I solved this with pull request #45 - but the signup.html and signup.js files must be updated in the shared S3 bucket, otherwise you need to replace them manually after the CloudFormation script.
