Overview

Set default values to avoid notices when rendering (event templates screen)

Before

On the manage event templates screen, if an event template had participant listings disabled (i.e. no value set), then a notice would be thrown from the Smarty template.

After

No notice is thrown.

Additionally, the "Participant listing" column now contains the text "Disabled", rather than an empty cell, which matches the language used on the edit form.

Comments

Default values have also been added for participant_role and event_type. These are required fields and so should always be set, however as there are if around where these keys are set it feels like it doesn't hurt to add the fallback values - it could catch edge-cases where event templates have been created through the API, or through poorly behaved extensions for example.
