Item1401: SlideShowPlugin doesn't work well in persistent environments

Priority:	CurrentState:	AppliesTo:	Component:	WaitingFor:
Normal	Closed	Extension	SlideShowPlugin

I was making a presentation with SlideShowPlugin on Foswiki+FastCGI and in the first time I pressed Start Presentation button, everything went fine. From the second time on the presentation didn't work.

The problem is that it uses some global variables, specially $addedHead, that is adjusted to 1 and then the method _addHeader simply returns. The fix is pretty easy: initialize $addedHead in initPlugin, that is called for each request.
