[Help-smalltalk] Magritte ported to GNU Smalltalk

[Paolo Bonzini]

I committed a port of Magritte and of the Seaside bindings to Magritte. 
 This highlighted a few bugs (in the class library and in gst-convert) 
and provided a better stress test for the Seaside/Swazoo pair.

You can test Magritte-Seaside by doing

  gst-package --start Seaside Magritte-Seaside

and pointing your browser to http://localhost:8080/seaside/editor.
