[ale] libale guile backend runs a simple client

[David Hilvert]

The libale guile backend now runs a simple client.  To try this, do

git-clone git://repo.or.cz/libale.git
cd libale
./bootstrap
./configure
make
./beer

An unfinished GLSL backend can also be run with:

./beer --glsl

Note that the bootstrap script requires the following:

autoconf-archive
autoconf
automake
libtool
swig

These can be installed with 'apt-get install <name>' on most apt-enabled
systems.

Other packages required for build are listed in the README.

If I have forgotten anything, or if anything breaks, please send bug reports or
(if possible) patches to ale at ventricle.dyndns.org .
