/**
* Utility class for creating new RC entries
*
* mAttribs:
* rc_id id of the row in the recentchanges table
* rc_timestamp time the entry was made
* rc_namespace namespace #
* rc_title non-prefixed db key
* rc_type is new entry, used to determine whether updating is necessary
* rc_source string representation of change source
* rc_minor is minor
* rc_cur_id page_id of associated page entry
* rc_user user id who made the entry
* rc_user_text user name who made the entry
* rc_actor actor id who made the entry
* rc_comment edit summary
* rc_this_oldid rev_id associated with this entry (or zero)
* rc_last_oldid rev_id associated with the entry before this one (or zero)
* rc_bot is bot, hidden
* rc_ip IP address of the user in dotted quad notation
* rc_new obsolete, use rc_type==RC_NEW
* rc_patrolled boolean whether or not someone has marked this edit as patrolled
* rc_old_len integer byte length of the text before the edit
* rc_new_len the same after the edit
* rc_deleted partial deletion
* rc_logid the log_id value for this log entry (or zero)
* rc_log_type the log type (or null)
* rc_log_action the log action (or null)
* rc_params log params
*
* mExtra:
* prefixedDBkey prefixed db key, used by external app via msg queue
* lastTimestamp timestamp of previous entry, used in WHERE clause during update
* oldSize text size before the change
* newSize text size after the change
* pageStatus status of the page: created, deleted, moved, restored, changed
*
* temporary: not stored in the database
* notificationtimestamp
* numberofWatchingusers
*
* @todo Deprecate access to mAttribs (direct or via getAttributes). Right now
* we're having to include both rc_comment and rc_comment_text/rc_comment_data
* so random crap works right.
