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.
Added the necessary classes to send email summaries. First, added a
script to run on a daily basis. Second, added a queue handler for
sending email summaries for users, and another to queue summaries for
all users on the site. Fixed up the email_summary_status table to
store the last-sent notice id, rather than a datetime (since we don't
support 'since' parameters anymore). Finally, made the plugin class
load the right modules when needed.
