MyBB 1.8 fix for showthread_noreplies template
Increase max filename in attachments to 255 chars.
Not officially supported, as MyBB doesn't do it, so won't put it in the upgrader - only changing because it was reported: http://mybbhacks.zingaburga.com/showthread.php?tid=4735&pid=17631#pid17631

Disable interlacing in JPEG output for thumbnails.
Thanks to leefish [http://mybbhacks.zingaburga.com/showthread.php?tid=861&pid=17007#pid17007] for the suggestion
Note down that showthread_noreplies only works if there's a corresponding postbit_first template being used
Thanks to Sama34 for raising
