/*
Plug-in Sniffer
----------------------------------------

This tries to detect the following plug-ins:
Flash
QuickTime
RealPlayer
Windows Media

Also attempts to ascertain the version of the Flash plug-in if 
installed. Gives version = 0 for the other plug-ins.

Sets the following variables:
hasPlugin (defaults to false if it can't detect)
pluginVersion (defaults to 0 if it can't detect)

Use this by calling the pluginExists() function, passing plug-in you 
want to check as a parameter, e.g.
pluginExists('flash')
pluginExists('quicktime')
pluginExists('realplayer')
pluginExists('windowsmedia')

Fails in the following browsers (i.e. defaults to hasPlugin = false 
& pluginVersion = 0);
Internet Explorer 4.x (Macintosh only)
Internet Explorer 3.x
No way around this as far as I know.
