Include Table piwik_log_action in Purge

The table piwik_pog_action should be included in the “Delete old visitor logs from database” function.

On my System piwik_pog_action is the biggest table with 831 Mb.
piwik_log_link_visit_action is only 481,6 Mb and piwik_log_visit is 170,1 Mb.

My settings:
Delete logs older: 30 Days
Delete Logs every day

damn my piwik_log_action table 30 million records already, dun know how to purge old records, no datetime columns, thats bad.
