Images didn't properly update their start time for icon animations when changing icons/states.

This issue has been resolved.
Play once animations are no longer resetting their play time when shown on an /image or an /obj after the 1342 update.

I'll send some code along in a few that demonstrates this.
Eep! This is definitely a must-fix for the stable release.
Play the following game in 1341 and then boot it up in 1342:

You'll notice that the sword doesn't animate after the first time you swing it in 1342.

Will PM the code on request.
I actually see the same issue in 1341.
