Automated DB Update & String Conversion for check_db.py

[sjdoescoding]

1. Created a workfile to automate the DB update process, it is not on an IF basis but rather WILL update the DB every midnight.

The PR function of the workfile hasn't been fully tested, but should be fairly easy to edit so it PRs the development branch for merging (like 1-2 lines of code).

2. Modified the check_db.py file by creating a function that will convert empty strings ' ' to a float 0.0 as this was having issues during testing. Seems to work fine but can be reverted easily and retested. If the site requires an int figure then you can just remove the float conversion function and theoretically it should still work just fine.
