adds a 'discard all' button at the bottom of the pending posts page, usefull for lists with high spam rate.

not sure if this feature is of general interest, people in the projects where we applied this patch feel confortable with it.

Could this perhaps be closed as it's quite similar in effect to
810675, which was included in 2.1.5?
