In some brief tests, this causes no problems.
In this state however, you would need to modify DB_DataObject to have a static declaration of staticget (and probably pkeyGet). The next commit will change the staticGet overload to a unique function name (like getKV for getKeyValue), which means we can properly call the function by PHP Strict Standards.
We need to bundle counts of notices and users by date. This can be
expensive for large sites. So, new tables are added to cache the
results of these queries, which don't change after the date is over.
