Wolfchev's Laboratory Instance Release.
Removed enchantments from const since they're in item_db.conf
Fixed several files with a missing EOL at EOF

- All text files should end with an EOL. Period.
- See http://robots.thoughtbot.com/no-newline-at-end-of-file for info
  on how to configure the most common text editors to do it
  automatically for you.

Fixed some charset issues

- Fixed files with mixed character set or invalid CP949 characters.
- Uncommented '#music' script in the_sign_quest.txt (now the
  soundeffect filename should be fixed).
- Added a note to the header of CP949 files not to read or save them as
  UTF8, since it'd break their encoding. It should be safe enough to
  read them as EUC-KR if your text editor doesn't offer CP949 as an
  option.
- Added FIXME notes about untranslated strings in assassin_skills.txt
  and WolfchevLaboratory.txt.

Partial cleanup of script_commands.txt

- Updated examples to a more modern syntax
- Corrected examples using the wrong case for script commands (fixes
  bugreport:8192 thanks to jaBote)
  http://hercules.ws/board/tracker/issue-8192-camelcase-in-scripting-documentation/
- Reworded or rewritten some misleading/no longer correct notes to match
  the current script engine behavior.
- Marked some commands as deprecated and suggested alternatives, to
  discourage their use in new scripts (set, goto, jump_zero, menu)
- Changed use of temporary character variables into scope variables in
  examples, where appropriate.
