Implemented the log-barrier constraint algorithm gradient and Hessian.

This implements equations 17.25 and 17.26 of Nocedal J. and Wright S. J. (1999), Numerical
Optimisation, Springer Series in Operations Research. Springer-Verlag, New York.

Fixes for grid search printouts when the verbosity level is >= 2.

The parameter values for each grid point was being printed out as the minimum parameter values
rather than the current parameter values.

Updated the minfx homepage http://home.gna.org/minfx/ to version 1.0.9.

Updated the version numbers to 1.0.9.

Backported the 1.0.9 tag CHANGES file to trunk.

The command used was:
svn merge -r164:165 svn+ssh://bugman@.../svn/minfx/tags/1.0.9 .

Updated the CHANGES file for minfx 1.0.9.

Minfx version 1.0.9.

This is a minor bugfix release which fixes the grid search splitting algorithm for parallelisation
when only one grid point is present.

Bug fix for the minfx grid.grid_split() function for when only one grid point exists.

This was previously only yielding a single subdivision consisting of NaN values. The situation is
now caught and the single grid point is set to the half way point between the upper and lower
bounds.

Removed all details about Freecode from the release checklist.

The old minfx links are still there (http://freecode.com/projects/minfx), but Freecode is dead
(http://freecode.com/about).

Backported the 1.0.8 tag CHANGES file to trunk.

The command used was:
svn merge -r157:158 svn+ssh://bugman@.../svn/minfx/tags/1.0.8 .
