Changes to 1.0.1

Syntax and semantical changes are marked with CHANGE:

* GNOME version can now show listing of all user defined global and local
  variables (can display this even while the engine is running, including
  a "backtrace" to aid debugging)
* GNOME version can now check if too much memory is being used and allows
  the user to interrupt the program rather than eat all available memory
  causing the computer to grind to a halt.
* When printing floating point numbers always make sure it is obvious that
  these are floating point by appending .0 when they would look like integers.
* Matrix printing is much nicer now, and possible to copy and paste back in
* Add IsMatrixPositive, IsMatrixNonnegative, version, IsZero, IsIdentity,
  DividePoly, IsSubset
* PivotColumns and NullSpace are built in for greater speed.
* CHANGE: Drop the support for tab as a matrix separator, it didn't
  work properly, especialy not on the command line
* CHANGE: Remove IsGaussianInteger, we already have IsGaussInteger alias
  IsComplexInteger
* CHANGE: OrthogonalComplement is with respect to the Hermitian product
* CHANGE: display, printn and print don't follow FullExpressions=false
* The .desktop file now has different Categories setup so will likely appear
  in "Education" or "Accessories" menu rather than "Office"
* Chop small numbers when they appear near other larger numbers.  New
  parameters OutputChopExponent and OutputChopWhenExponent
* Fix set theory functions by essentially fixing IsIn.  Also fully document
  the behaviour of the set theory functions.
* Update the plotting widgetry from GtkExtra for prettier graphs
  (Sebastian Dröge, me)
* Add "Save all unsaved" menu item
* Add Ctrl->R for "Run"
* Default graphing limits are -10 to 10 for all axis (no more pi as default)
* Require at least GKT+ 2.4 for the GUI.
* Optionally compile with GtkSourceview2 and drop back to
  GtkSourceview1 if unavailable (Sebastian Dröge)
* Fit dependent axis works for parametric plots
* Legend more readable for parametric plots
* Fix loading of files and URIs from the command line
* Errors don't print the full file URI for opened program names
* Confirm closing unsaved programs
* Lots of documentation updates
* Use Binreloc 2.0 so that the package is relocatable
* Slight optimizations
* Handle null in more linear algebra function as an empty matrix/subspace
* Fix command line editting
* Fix showing full answer in the gui.
* Fix hangs in the graphing code by enforcing a minimum plot window size
* Consistently traverse matrices row-wise everywhere
* Remove unused file with nonfree license
* Add --disable-scrollkeeper and --disable-update-mimedb to configure
  (Sebastian Dröge)
* Update the about box
* Updated translations (Jorge Gonzales, et moi)
