[Feature Request] Option for automatic removal of downloaded filelists if "Match downloaded lists" returns 0 matched files for them

[LoRenZo]

I think this feature would come handy if users (such as myself) keep the downloaded fileslist by default for browsing them later on for whatever reason. Currently I remove those which do not contain any matches with my queue list manually in order to keep my drive clean and speed up the matching process - the others ones I still want to keep as long as they contain any matches.

If this is going to be implemented, it should be turned off by default in my opinion.

Since customizing options are not preferred in DC++ these days, this is something that the plugins can solve later...
