Chat commands disabled for normal players.

A new setting for the world server has been added. From now on
chat commands executed by normal player accounts will no longer
be executed, unless you explicitly enable the `PlayerCommands`
option.

By default player command execution is disabled.

Use proper path in usage examples.

Tools expect the World of Warcraft installation directory, not any
subdirectory.
