Function oldz is deprecated

The oldz function is deprecated. It may not be supported by newer versions of Ultra Fractal. Instead of oldz, use an array of complex numbers to store old values of z.

Do not use oldz in new formulas, and update old formulas so they use an array instead. Example:

init:
  complex z_values[#maxiter + 1]
  int i = 0
  z_values[0] = #z
loop:
  i = i + 1
  z_values[i] = #z
final:
  ; z_values[] is now equivalent to oldz()
