Improve the connection tracking selection (well, the user experience,
not really the aesthetics) by offering one option to enable connection
tracking and a choice between the implementations.

Connection tracking keeps a record of what packets have passed
through your machine, in order to figure out how they are related
into connections.
This is required to do Masquerading or other kinds of Network
Address Translation (except for Fast NAT). It can also be used to
enhance packet filtering (see `Connection state match support'
below).
