Update to FriCAS 1.2.7

Changes:

- New package implementing van Hoej factorization algorithm
  for LODO-s.

- Gcd over Expression(Integer) now uses modular method.

- Improvements to integrator, in partucular trigonomoetric
  functions are consistently integrated via transformation
  to complex exponentials.

- Some categories and domains are more general. In particular
  OrderedFreeMonoid is removed, as ordered case is handled
  by FreeMonoid.

  renamed to  FreeMagma.

Bug fixes, in particular:

- Coercion of square matrices to polynomials is fixed.

- Problem with division by 0 in derivative of 'ellipticPi'
  is fixed.

  when coefficients were power series.
