Add logical not operator in walk operations

Remove from input using the ! operator at the start of the expression. Things are very messy, and syntax is in flux, but at least !/foo/bar Will remove /foo/bar from the input !/foo/bar,baz Will remove /foo/bar and foo/baz from the input !(/foo),(/bar/baz) Will remove /foo and /bar/baz from the input. This is highly experimental for now. Signed-off-by: Pantelis Antoniou <[email protected]>
