Subject: [PATCH] object.c ruby.h (fwd)

Hello everybody,

my name is Robert Skarwecki and this is my first contribution to the Ruby
development.

The patch implements the ToDo task "introduce Boolean class; super of
TrueClass, FalseClass".

A quick test shows the result:
$ ruby -e "puts true.class.ancestors.join(',')"
TrueClass,Object,Kernel
$ ./ruby -e "puts true.class.ancestors.join(',')"
TrueClass,BooleanClass,Object,Kernel

Here are the patched files. Do they reflect the finished state of the task
or is there anything else left to do, if so, what is it ?
