Trackbacks and pingbacks are a pain, and we don't need/want/use them. Turn them off.
The place(s) to edit this and other defaults:
/inc/CONTROL/collections/blogs.php (lines 165-178)
/inc/MODEL/collections/_blog.funcs.php (lines 51-73)
NOTE: I'm going to work on this as part of the deployment of 1.9.2 rather than in the current version. If anyone wants to take this task and complete it on 1.8, go right ahead.
NOTE: I believe this is now done.
