[Chicken-users] Update: amb.egg v1.2.0

[Thomas Chust]

Hello,

I tweaked my amb egg a little to make it more useful: non-determinism 
is now optional and the scope of operation for amb can be controlled 
easier.

The changes in detail:
- amb is now called amb/random
- amb does the same as before except it doesn't shuffle the list of
  expressions any more
- an amb-find macro has been added
- the documentation has been updated accordingly

The changes are applied in the Subversion repository and a new version of 
the egg is also on my website at
    http://www.chust.org/projects/amb.egg
The documentation can be found at

cu,
Thomas
