v1.6.0 Linux & Windows

New features

• HWID (Unique Machine Identifier). Reliably obtain a client's hardware id on the server.
  New natives ncl_get_client_hwid(id, hwid[], len) and ncl_is_hwid_received(id), and a new
  forward ncl_hwid_received(id, const hwid[]). HWID is delivered by NextClient 2.5.0 and above;
  NCL_HWID_LENGTH is 64.
• Mouse inversion. New native ncl_invert_mouse(id, bool:invert_pitch, bool:invert_yaw) to
  invert the pitch and/or yaw mouse axes of the client.
• Weapon sound override. New natives ncl_override_weapon_sound(weapon_id, const original[], const replacement[])
  and ncl_override_weapon_sound_clear(weapon_id) to replace the sound of a specific weapon entity.
• New sandboxed cvars: viewmodel_fov, cl_bob_camera, hud_deathnotice_max.
• Connection logging. Each NextClient connection is now logged with name, SteamID, HWID,
  address, version and its verified/compatible state.

Removed / deprecated

• Removed legacy _ncl client detection. ncl_is_next_client is deprecated: it is no longer
  declared in the include and always returns NOT_NEXT_CLIENT. Already-compiled plugins keep working.
