Added mod_chat_history_sqlite and mod_chat_is_privileged.
Use file=/path/to/db to specify the database file where chat history should be stored. Other config variables are the same as those for mod_chat_history. Code merged adapted and merged from Mimicmod's repository: https://github.com/mimicmod/uhub.git
