What you want is already available in the advanced search dialog, where you 
can save a search for later re-use.

Implementing it in the filter tab might have some unexpected effects:
in the case of multiple selected tags, do you want 
NOT (tag1 OR tag2 OR tag3) or
(NOT tag1) OR (NOT tag2) OR (NOT tag3);
same question with AND instead of OR.

While it may be handy for some simple cases, very quickly the effects might 
not be at all what you want. Or the tab gets a lot more complicated.

That said, it might be handy to have a NOT option for the colour flags, 
depending on how you use them.
