sci-mathematics/giac: new package for the Giac/Xcas math systems.

We have bugzilla requests for this package going back to 2005! The
SageMath suite has recently gained the ability to use Giac from the
system, so now is an especially good time to add it to the tree.
François Bissey has been maintaining this package for years in the
sage-on-gentoo overlay and contributing fixes upstream, so the ebuild
required only minor changes at this point. I personally thank him and
you should too.

+    Giac is a free computer algebra system that can be used to perform
+    computer algebra, function graphs, interactive geometry (2-d and
+    3-d), spreadsheet and statistics, programmation. It may be used as
+    a replacement for high end graphic calculators for example on
+    netbooks (for about the same price as a calculator but with much
+    more performances).
