Added a new Jamfile rule, called SubIncludeGPL, which can be used to conditionally

include GPL licensed add-ons into the build. As GPL licensed add-ons may not be
used with non GPL compatible applications, this rule normally is not invoked when
building the tree. However, if the user is sure that he only uses GPL compatible
software, he can use the new ./configure option --include-gpl-addons to enable
the including of GPL licensed addons that are integrated by SubIncludeGPL instead
of SubInclude.
