• Added a new docs/LICENSE describing non-commercial terms and mudlib/user-space scope.
• Removed the bundled GPLv2 text file (docs/GPLv2_LICENSE).

docs/Copyright.MudOS:22

• This file no longer states that Neolith is distributed under GPLv2, but the repository README still links to docs/GPLv2_LICENSE (which this PR deletes). That will leave a broken link and conflicting license documentation unless the README is updated (or an alternative license reference is provided).
