Version 1.0.22 released.

• Fixed the combination of Mode = router and DeviceType = tap.
• The $NAME variable is now set in subnet-up/down scripts.
• Tinc now gives an error when unknown options are given on the command line.
• Tinc now correctly handles a space between a short command line option and an optional argument.

Thanks to Etienne Dechamps for his contribution to this version of tinc.
