Summary:                    [patch] Floating point exception crash when saying
number between 9999 and 100000 with zh or tw language
Description: 
Issue 12319 introduced some new code to say.c to make saying numbers in
Chinese more correct... This code causes an asterisk crash when trying to
say a number between 10000 and 99999 inclusive.

The crash occurs in ast_say_number_full_tw in say.c when performing 
if (((num / 10000) % (num/100000)) == 0)
  playz++;
in the section of code that deal with numbers between 10000 and 100000000,
which, for numbers below 100000 results in a divide by zero issue due to it
being an integer operator causing an untrapped floating point exception.
