MyBB forum platform integration

A pgn4web user reported success integrating pgn4web with the MyBB forum platform.

The suggested guideline starts from the configuration pages of MyBB, mycode section, add new mycode action:

• for the regular expression use \[pgn\](.*?)\[/pgn\]
• for the replacement use the same HTML code suggested for the simplemachines integration, replacing {content} with $1
