Pingbacks/Trackbacks are enabled for topics and forums

[netweb]

A couple of recent reports from the bbpress.org forums people are getting pingback/trackbacks to forums and topics:

http://bbpress.org/forums/topic/comments-on-topics/#post-151748

http://bbpress.org/forums/topic/disable-pingbacks/

Needs further investigation as there are numerous instances in bbPress where these are supposed to be closed for the three custom post types and also in the converter/import.

By default pings are 'open' for bbPress post types, if you don't want pingbacks or trackbacks showing don't approve theme in the comments panel.

Attached patch is a first pass at setting ping_status to closed, replicates existing comments closed_status for pingback/tracbacks.

Moving this to 2.7 alsongside #1430 "Show pingbacks on topic page" as some work will be needed in having all this work well together.
