Please Add Auto Clean Feature

[Poveretto]

1.Normal mode - be cycled to clean clipboard (user-custom time span)
2.Blacklist mode - intergrated with KEYWORDFILTER
(2.1 clean clipboard once apps in blacklist access to clipboard --no KEYWORD
2.2 When use apps in blacklist, clean specific item if KEYWORDFILTER is on)

I don't think we could know which apps are accessing the clipboard. Thus blacklist mode is impossible.
