Rename several mean functions

Renamed the following functions:

* GeoMean function overloads => GeometricMean.

* WeightedGeoMean function overloads => WeightedGeometricMean.

* ArithMean function overloads => ArithmeticMean.

* WeightedArithMean function overloads => WeightedArithmeticMean.

Updated affected source code .dat files. Updated all references to old names
in maths.ini meta data file.

Regenerated UMathsCatSnippets unit from CodeSnip to rename all references to the
renamed functions.

Revised TestUMathsCatSnippets to use the new function names. Also renamed the
unit test methods to reflect the changed function names.
