Update to FriCAS 1.1.1

Notable changes since version 1.1.0:

- New graphics framework.
- Support for using GMP with sbcl on 32/64 bit AMD/Intel processors
  (to activate it one must use '--with-gmp' option to configure).
- Improvements to integration and normalization.  In particular
  integrals containing multiple non-nested roots should now work
  much faster.  Also FriCAS now can compute more integrals
  of Liouvillian functions.
- Several new special functions.
- Improvements to efricas.
- Looking for default init file FriCAS now first tries to use
  '.fricas.input' and only if that fails it looks for
  '.axiom.input'.

Bug fixes, in particular:

- Numeric atan, asin and acos took wrong branch.
- WeierstrassPreparation package did not work.
- Saving and restoring history should be now more reliable.
- Fixed two bugs in Spad compiler related to conditional compilation.
- Fixed a problem with rational reconstruction which affected
  guessing package.
