Changes to recomb.c to ensure that integrals converge when computing the recombination rates for very cold plasmas with the new extrap topbase data which extends to very high frequencies
Changed the range of temperatures in init_freeboud to take account of hotter X-ray plasmas - also increased the number of temperatures that freebound is calculated for from 30 to 60 to keep the lower temperature discretization the same.
Modifications to the cloudy table banding - now many more bands to ensure proper sampling
Small change to avoid compilation warnining of unitialised variable
