table {comments} prefix braces missing from karma.module

Issue Summary

As per this post: http://drupal.org/node/175553

SELECT DISTINCT(nid) FROM comments
needs changed to
SELECT DISTINCT(nid) FROM {comments}

and also

FROM comments c LEFT JOIN karma_objects
needs changed to
FROM {comments} c LEFT JOIN {karma_objects}

There was a third that I found that I can't find offhand, but if you just search "FROM comments" with your editor, you'll find all three.

Cheers!
