Forum upgrade

[DaveS]

I've upgraded to the latest version of the forum software.

Here's a list of things that have been added in this release:

• Social group discussions
• Social group categories
• Private message sorting and filtering
• Private message history
• Quick edit for newer types of content (visitor messages and picture comments)
• Social group icons
• Social group transfers
• Private message quick reply
• Private message throttling (limit messages sent over a time period)
• Private message reporting
• Profile privacy (limit blocks to a subset of users)
• Lightbox navigation
• Thread prefix permissions
• Dismissible notices

Enjoy!
