Fixed: corrected the leading order in the asymptotics for \rho_1 in
       theorem 1.2.
Fixed: The clusters in the cluster expansion are multi-sets, not sets.
Fixed: The Ursell function in lemma 3.3 needs to be divided by the
       multiplicity of each element.
Fixed: In the proofs of lemma 3.4 and theorem 1.2, when individuating a
       polymer from a cluster, one needs to sum over its multiplicity so
       as to avoid overcounting.
Fixed: Wrong estimate in the proof of lemma 3.4 which changes some of the
       constants.
Fixed: Missing a smallness condition on \alpha in the proof of lemma 3.4.
Fixed: Wrong argument for the analyticity of \zeta in the proof of
       theorem 1.2.
Fixed: miscellaneous minor tweaks, reformulations, clarifications and
       typos.
