Future Post Dates on Events do not effect anything

[andypullen]

Describe the bug or issue you're experiencing
Setting the Post Date of an Event to a future date does not change the status of the Event like other Craft entries do. Additionally, the postDate is not accessible in twig templates, so building queries to exclude Events with future Post Dates is also not possible.

Steps to reproduce

1. Create an Event with a future Post Date
2. Note that the Event status does not change to Pending, but is Live instead

Expected behavior

• Putting a future date in the Post Date field should change the Event status to Pending
• Pending Events should not be included in frontend Event queries by default
• The postDate value should be included in the Event object in twig
