removed GAP4.4 legacy stuff from init.g and read.g
enhanced HomalgFieldOfIntegersInSingular to access all finite fields
used GaloisField( p ) instead of Integers( p )

which causes segfaults
simplified code in CommonHomalgTableForMAGMATools.Eliminate
added CommonHomalgTableForMAGMATools.PrimaryDecompostion
simplified code of homalgTable entry PrimaryDecomposition

in CommonHomalgTableForMAGMATools and CommonHomalgTableForSingularTools
added new entry RadicalDecomposition to CommonHomalgTableForMAGMATools
added new entry AffineDimensionOfIdeal to CommonHomalgTableForMAGMATools
