No filter to disable single forum description exists

[naxoc]

There is currently no way to avoid calculating all the stats for the "This forum has x topics, x replies, and was last updated x mins by x." above forums. There is already a filter to _alter_ it, but no way to avoid doing all those calculations.

Well, yes. There is a way by removing the call to bbp_single_forum_description() from templates, but it would be nice to be able to filter if it should happen.

This patch adds a bbp_use_single_forum_description filter that is checked before starting calling the function that gathers the data.
