- fixed 3143317 -- plug-in supplied URLs cause correspondingly named files in /tmp to be deleted
	- fixed 3143330 -- plug-in supplied URLs can overwrite files used in other windows by same plug-in

        * Plugins.subproj/WebBaseNetscapePluginStream.h: Make path be a char * rather than an NSString.
        * Plugins.subproj/WebBaseNetscapePluginStream.m:
        (-[WebBaseNetscapePluginStream dealloc]): Use unlink() to delete the temporary file we made.
	Since we created the file, we know it doesn't have any fancy stuff like a resource fork.
        (-[WebBaseNetscapePluginStream finishedLoadingWithData:]): Create the file with mkstemp instead of
	trying to come up with our own filename. This eliminates the need to delete an old file (because we
	are guaranteed the file is new) and also mkstemp opens the file for us, so we just need to write
	the contents.

        * English.lproj/StringsNotToBeLocalized.txt: Updated for above changes.

        - unrelated change to help with other bug analysis

        * WebView.subproj/WebBaseResourceHandleDelegate.m: Added assertions.
