Expected Behavior

Running play new-module test should create the new module

Actual Behavior

Running play new-module test is failing:

$ play new-module test
~        _            _
~  _ __ | | __ _ _  _| |
~ | '_ \| |/ _' | || |_|

~ play! 1.6.1, https://www.playframework.com
~
~ The new module will be created in /home/jsh/devel/play-modules/test

    status = cmdloader.commands[play_command].execute(command=play_command, app=play_app, args=remaining_args, env=play_env, cmdloader=cmdloader)

    replaceAll(os.path.join(app.path, 'conf/routes'), r'%MODULE_LOWERCASE%', string.lower(application_name))
AttributeError: module 'string' has no attribute 'lower'

Moreover the resources/module-skel/commands.py file should be updated to be compatible with python3.
