Customizable script to allow honor from creature kills

* See CONF section: CUSTOM SERVER OPTIONS - CREATURE HONOR
* For existing servers, please import: characters_create_creaturehonor_message.sql
* Made a change to CMakeLists.txt which allows inclusion of custom scripts. Re-run CMake if you're not starting fresh.
what's the point of filling the table only for new created players and if the script is enabled ? after all a row with default value 0 is the same as not having a row at all
