config.sh.repo: DAYS_TO_KEEP

* Renamed "NIGHTS_TO_KEEP" to "DAYS_TO_KEEP" since it determines how many days' data is kept, not just nighttime data.
* Removed the "AUTO_DELETE" variable; instead, if "DAYS_TO_KEEP" is "", then all days are kept, otherwise only the specified number of days are kept.  This eliminates one variable while keeping the old functionality.
* Added "WEB_DAYS_TO_KEEP" to clean out the Allsky website files.
