added a test for dim() for rings over integers
fix dim test
fix dim test again
added the 'dim-test_for_rings_over_integers.tst' to 'Short.lst', also now the test file ends with a '$'
scrambled hostname in stat file
improved genus documentation for 1-dim affine variety input
chg: added new conversion for polys over Fq (requires FLINT at least 2.4)

Conflicts:

chg: use for univariate factorization over Fq
chg: use FLINT instead of NTL in squarefree factorization
chg: first part of changes in facMul
chg: second part of changes to facMul.cc
chg: use FLINT to factorize polys over Fq in facFqBivar
chg: fixes to stay backward compatible
bug fix due to unset NTL characteristic
fix: converting the wrong poly to FLINT
chg: more concise functions for Kronecker substitution and reversion of the very same
fix: bug in computing bounds for factor recombination
fix: compiler warning in case FLINT >= 2.4 is around
chg: new function to get coeffs over extension with FLINT
chg: replace NTL by FLINT in bivariate factorization over FF in case a field extension is needed
