[Igiss]

Cyrodiil forums were updated today to Simple Machines Forum v1.1.3.

Fixes implemented in the current version:

- Sending newsletters could cause a timeout on large boards.
- Reporting a personal message needed some more sanitation.
- Session fixation could, in rare cases, be applied - reported by David Vieira-Kurz.
- Prevent recursive functions from causing a stack overflow in PHP - reported by Stefan Esser.
- Fixed a bug causing some expressions to trigger an error in UTF-8 mode.
- Quick edit wasn't updating the subject correctly if it was the first message.
- The package manager could in rare cases get itself into a loop.
- Characters weren't properly escaped in [html] parts of the signature.
- Quick edit didn't check whether a topic was being locked.
