* Unify OS_FILE_ILLEGAL_CHARACTERS * Provide KNOWN_PATH_SEPARATORS in addition to FILE_PATH_SEPARATOR. * Update nsExternalAppHandler to use KNOWN_PATH_SEPARATORS instead of FILE_PATH_SEPARATOR when removing path separators. * Fix DownloadsIPC.jsm when compiling with MOZ_DEBUG (would throw on undefined download.id). * Add test for stripping out illegal characters when downloading.
