Summary description: Knuth Fibonacci multiplication, Zeckendorf and Bergman representations of big integers

Announcement text:
----------------------------------------------------------------------

This adds many new features and has some breaking changes due to
renamings, not listed here.

- It is not \xintiieval but \xinteval's syntax which is now
  extended.

- Variables phi and psi are defined and one can do algebra with +,
  -, *, and ^ on them in Q(phi).

- The Bergman phi-representation is added for elements of
  Z[phi] in particular for integers.

- The $ character doing the Knuth Fibonacci multiplication on
  positive integers now uses the (more efficient) Arnoux formula.
  The $$ computes out of deference according to the Knuth formula.

- The PDF documentation section on the mathematical background has
  been extended and includes bibliographical references.

- The interactive interface integrates all novelties.
