Changes to 0.7.2

* The manual is in Docbook and has been greatly updated (Kai Willadsen, me)
  there is even the beginnings of a detailed function reference with links
  to Planetmath and Mathworld.
* Better help integration
* We have an icon (Eugenia Loli-Queru)
* Include internal MPFR which is more recent and less buggy then ones
  found on most people's systems (this makes it easier to compile genius
  too)
* Added: CompositeSimpsonsRuleTolerance, GaussFunction, GaussDistribution,
  BernoulliNumber, ExactDivision, MoebiusMu (Alessio Frusciante), 
  IsNonNegativeInteger, LUDecomposition (David W. Hutchison),
  EulersMethod, RungeKutta
* Fixed, round, ceil, trunc and Hofstadter
* Few more functions now apply over matrixes with matrix arguments
* CompositeSimpsonsRule and Divides are built in for speed
* Treat strings as constants, thus getting pretty good speedups where
  strings are used
* When new references are encountered where the variable does not exist we
  create the variable in the current context
* On the plot window use "y=" as a label to indicate what goes in the text
  boxes
* "New" toolbar item
* Fix crashes on non-number matrix multiplies
* Bunch of minor fixes all over
* Help texts are being translated now
* Translation updates (Adam Weinberger, David Lodge, Miloslav Trmac,
  Amanpreet Singh Alam, Raphael Higino, Vincent van Adrighem,
  Tino Meinen, Jan Morén, Laurent Dhima, Takeshi AIHANA,
  Francisco Javier F. Serrador)
