Charm needed: vBulletin

[Daniel Holbach]

It'd be great to charm up vBulletin, which would help the Ubuntu forums people to more actively take care of the vBulletin administration and test changes.

https://www.vbulletin.com/docs/html/ explains how to set it up.
https://www.vbulletin.com/docs/html/main/vb5_system_requirements explains the system requirements:
 - PHP version 5.3.0 or greater
 - MySQL 5.5 or greater.
 - cURL or OpenSSL support – Allows secure connections to third-party services like Facebook Connect.
 - MySQLi support – MySQLi is a more robust software library to connect to the database that vBulletin uses.
 - Iconv support – A library that provides extra language and character set support.
 - OpCode Cache – An OpCode Cache like APC or XCache will enhance the performance of your vBulletin software. An OpCode Cache is a caching mechanism that can significantly increase the performance of vBulletin by pre-parsing the PHP files and keeping commonly used data in memory for rapid retrieval.
