#1 autoconf/automake/libtool patch

[Anonymous]

Hi,

Here is a diff to enable autoconf configuration and
compilation of cel. It uses libtool to generate plugins
in order to ensure better portability.

I tested the resulting distribution with planeshift and
it runs. However, because of the non cannonical nature
of the original configuration/compilation system, I
kept the old Makefile.

With the current patch, if people chose not to use
autoconf, the previous method still works unchanged.

The patch also fix the FSF address in the license
notices and adds the COPYING file promised but not
included.

Enjoy,
