geography/gama: Update to 2.04

Despite the version jump from 1 to 2, the changes are relatively
small, consisting mostly of various minor improvements and bugfixes.
Notable items are:

* The new attribute "extern" suggested by Kristian Evers (Danish
  Agency for Data Supply and Efficiency) was added both to the
  gama-local xml input and adjustment results xml output to be
  conformant with an external database project. Information supplied in
  "extern" attributes of observations are not processed in any way in
  gama-local and are only passively transfered to XML adjustement
  output.

* Improved Hungarian translation by Siki Zoltan:

* Kolmogorov-Smirnov test removed - available only as conditional
