filter-apply: Make housekeeping optional

Browse source 
Adds an autoclean option (defaults to TRUE) that controls whether
module-filter-apply cleans up unused modules or not. This is useful in
cases where you know that a filter will be used often and thus can avoid
overhead from repeated module load/unload.
