Extended support for MySQL 5.7

MySQL 5.7 has changed how the TIMESTAMP column works. They now require a default value to be set, or they must be explicitly set to a NULLable.

This release sets the masterlock table to have the created_at and last_updated TIMESTAMP columns to be NULLable, thus extending support for MySQL 5.7.
