Title: Add :Acks

Run the specified substitution command on all the files in the quickfix
list (mnemonic: "Ack substitute").

Specifically, the sequence:

:Ack foo
:Acks /foo/bar/

is equivalent to:

:Ack foo
:Qargs
:argdo %s/foo/bar/ge | update

(Note: there's nothing specific to Ack in this function; it's just named
this way for mnemonics, as it will most often be preceded by an :Ack
invocation.)
