Describe the bug
When adding a race, you get : MySQL Error: Field 'replay' doesn't have a default value. There appears to be two NOT NULL field on the 'race' table called 'reply' and 'simresults' but the form does not have a way to fill these out.

To Reproduce
Steps to reproduce the behavior:

1. Go to Login Admin
2. Click on Races
3. Click on Add Race
4. Fill out form and click 'Add'

Expected behavior
The race should be saved.

Additional context
It needs to be determines if these fields are needed or not. If they are needed, then a default or a way to edit the fields is required.

This fields "replay" and "simresults" aren't mandatory, they are to be fill when the race is over in: "Modify race results" where this fields can be edited, there you can fill results by hand or importing data from file created by the game #62, and optionally add a link to a replay and results uploaded to another optional page.
