Feature Request - automatic bib assignment during pre-reg import

[stuartlynne]

Could we get an event pre-reg import option to have RaceDB assign a Bib number for participants during import?

The assignment would be done from the allowed range for the registered category.

This would only be done if the participant does NOT already have a Bib assigned. I.e. for a series, they would have a Bib from the previous event in the series. Only people who have not done an event in the series would get assigned a Bib.

This would simplify registration for events, eliminating another (albeit small) step that registration volunteers have to do when checking people in.
