Updated versions of the kForth port of the FSL big.4th module and the 
extra definitions for big number arithmetic in big-extras.4th are now 
part of the kForth-64/32/Win32 repos on ccreweb.org and on github.com.

With regard to discussion of floating point output in recent threads, 
these Forth library codes can be used to implement a high quality 
REPRESENT capable of output of a large number of digits. They may also 
be used to perform accurate range reduction for large angle arguments to 
trigonometric functions.

     Revise FSL module big.4th and add big-extras.4th

       1. Increase big number output buffer size in big.4th
       2. Additional big number words provided in big-extras.4th

      On branch master
             modified:   forth-src/fsl/big.4th
             new file:   forth-src/fsl/extras/big-extras.4th
