New idea: a withlist

Hi,

My idea is a withlist with directorys or files, which mustn't be cleaned.
As an example: You activate the deepscan and compiled files. That meens all compiled python-files will be deleted. But close-source programs need them, because they don't give you the original python-script.

Second example: You clean logs from pidgin, but you want to keep a chatlog from a person.
