chatroom 6.x-2.10

Lots of fixes and some new features and a backwards-incompatible API change with this release.

• #193323: Chat Room only updates for each user when that user posts content
• #841392: Remove user link in the user list of private chat's doesn't work.
• #667384: User names linked to use profile page in chat window even if current user does not have access to user profiles
• #705288: Slow response times on messages
• #796172: Path to chatroom module directory is not obtained correctly
• #667392: Add admin settings for variable chatroom_online_list_timeout
• #267962: Private chats listed in the public arhive
• #661672: Chat room module two problems
• #848518: Rules creates Chat but chat doesn't work correctly.
• #834096: Chat time changes randomly

The last issue in the list introduced a change in the timestamps are stored, and usernames in messages themed.

If you want to over-ride the themeing of a username in a chat message, you now need to implement the 'chatroom_message_username' theme hook.

Thanks to everyone who reported a bug and/or provided a patch!
