SQL error - User Stats assumes Comment module is enabled.

If a user tries to add content (a node) with User Stats enabled and the core Comment module disabled, you will see an error similar to this:

PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'MYSITE.comment' doesn't exist: SELECT COUNT(*) FROM {comment} c INNER JOIN {node} n ON c.nid = n.nid WHERE c.uid = :uid AND c.status = 1 AND n.status = 1; Array ( [:uid] => 1 ) in user_stats_post_count_update() (line 958 of /sites/default/modules/user_stats/user_stats.module).

Patch attached resolves this error, although there may be a better solution.
