This is done in preparation for adding namespace support to the Ruby
part of SWIG. Some existing test cases were reorganized or duplicated
for flat/nonflat nesting. For some a Ruby test script was added.
Finally the ruby/Makefile.in was improved so that for test cases
without an explicit test script, the generated wrapper library will
be loaded by the Ruby interpreter to ensure loading works fine.
Added swig_assert.rb and started using it in some tests.
Added my patches to ruby.cxx, rubyrun.swg, rubystrings.swg
and rubytracking.swg [see: sourceforge]
