have float(huge) -> inf and float(1/huge) -> 0 instead of overflowing (correct or not, i tend to find this behavior more convenient). also work around a matplotlib limitation causing very large but not quite infinite floats (gradual overflow?) to raise an error

Faster implementation of elliptic functions; Jacobi theta functions admit complex parameter m; added jacobi_theta(n, z, q), which depends on the nome q, not on the parameter m; it is faster because in the former representation of the theta functions most of the time is spent in computing q from m.
