	* src/mathfunc.c: Implemented Affine Scaling algorithm for the
	Solver tool.

	* src/solver-lp.c: Switched the solver to use the affine scaling
	instead of the simplex.  Beautified the generated reports.

	* src/solver.h: Renamed some of the Solver constants.

	* src/analysis-tools.h: New file.  Moved stuff from
	src/dialog/dialogs.h.
