Update aliceml to use git version of Alice ML

This allows 64 bit builds of Alice ML and removes the need for old
versions of gcc to build.

The license is changed to 'mit' from the 'bsd' that it was previously
as the COPYING files in the alice and seam repositories appear to be
the modern style MIT variant (also known as the ICU variant).

Added myself as the maintainer.
