Allow users on front to block publication of advert

DJ-Classifieds users can now block publication of the advert. This is handy when they do not want to unpublish it but stop publishing it for a while.
To enable this feature go to Options - Global tab and enable "Allow users to block adverts" feature.

Once enabled user can block the advert and it'll disappear from the adverts list. Later when needed the advert can be brought back by publishing it again.
