Bait station record reports updated

The “bait taken” value is now calculated on-the-fly using the previous bait station record. Previously the bait taken amount was calculated when a record was added which meant the values would be incorrect if the records weren’t entered in chronological order.

A bait taken column has also been added to the table of records when viewing individual bait stations.

More bait station reporting - including map views - will be added soon.
