- fixed 3136797 -- crash when Adobe SVG Viewer plug-in puts up modal dialog

        * Plugins.subproj/WebBaseNetscapePluginView.h: Add inSetWindow boolean.
        * Plugins.subproj/WebBaseNetscapePluginView.m:
        (-[WebBaseNetscapePluginView sendEvent:]): Don't send any events to a plug-in while it's
	inside NPP_SetWindow. We don't want to implement more general reentrancy protection, because
	it could cause trouble for plugins that can handle it correctly, but it's unlikely that any
	legitimate use would require reentrant calls while inside NPP_SetWindow, and that's the case
	that crashes for the SVG viewer plug-in when it presents its registration dialog.
        (-[WebBaseNetscapePluginView setWindow]): Set boolean.
