Log Message:
many bug fixes and improvements such as:
* small improvement to Arg(...) working on real numbers.
* improved 'make test', no need to install before test any more.
* VarList can now accept a second argument, a filter predicate.
* Pattern     matcher     now    allows    extended    prototypes,    like
  PP(list_Contains("a")) <-- ... etcetera.
* c-style  tokenizer  using CTokenizer() (DefaultTokenizer() switches back
  to the default tokenizer).
* Great speed-up of function Assoc.
* Christian   Obrecht   implemented  the  Rabin-Miller  primality  testing
  algorithm, which greatly improves the speed of IsPrime.
* Orthogonal      polynomials     OrthoP,     OrthoP,OrthoG,OrthoH,OrthoL,
  OrthoT,OrthoU implemented by Serge Winitzki.
* various  speedups,  and  a  new memory manager, optimized for allocating
  many small blocks (which is the case in Yacas).
* Changed the directory structure for the script files
* Greatly improved Simplify function.
* Added CurrentFile, CurrentLine functions
* Implemented  backquote  mechanism:  `(...) will substitute every @a with
  the  evaluation  of  a  (and  if  a  is  a function the function name is
  replaced).  The  end  result  is  evaluated. see substitute.cpp for more
  details
