v1.1.2

[filipporomani]

Sorry for this release after only 13 hours, but many changes have been made.

• Version update: whatsapp-python now checks if a new version is available at every initialization. An error is logged if a new version is available;
• Logging disable: logging can now be disabled by passing the logger=False argument in the initialization;
• Unbound variables: a lot of possibly unbound variables are now properly handled;
• v15 API instead of v14;
• Significant docs improvements;
• pep8 formatting;
• Removed tests.
