set default value for timestamp fields to CURRENT_TIMESTAMP

[MrSnoozles]

Since MySQL 5.7 SQL mode "NO_ZERO_DATE" is enabled by default. That means date fields which are not nullable need a default value ("0000-00-00" is not allowed). Therefore we set the default value to CURRENT_TIMESTAMP so - unless specifically defined in the insert statement - the current timestamp will be used. I guess that makes sense for both created_at and updated_at.

I tested the installation and with those modifications it works without any errors. Still wondering about the schema-update-v*.sql files though. There are timestamp fields with default values 0000-00-00 00:00:00. They do not seem to cause any errors.

Thanks - I'll merge this in and make the same change to the updates for consistency.

Thanks - I've merged this in. Not updating the updates as you say they do work. Don't want to break anything either. 😃
