Non-enumerator related wordlists should be configurable

[stevecoward]

Currently the dirb http service module process is using a preset list of wordlists. If the user is not using enumerator on Kali Linux this may cause the dirb process to choke.

enumerator may wind up needing a config file to handle situations such as this, so this issue may be soon blocked by a higher priority enhancement to define a configuration file feature.
