Consistent branch cuts for complex numerical functions.

Package specfn psi (digamma) function can now be calculated numerically for complex arguments.

Package specfn New functions: theta1d, theta2d, theta3d and theta4d — numerical evaluation derivatives of theta functions.

Package specfn Weierstrass, WeierstrassZeta, sigma, sigma1, sigma2, sigma3 and sigma4 — rules and numerical code added.
