GoodbyeDPI v0.2.2

Bugfix release:

• Document forgotten --max-payload in -5 and -6 modes
• Allow setting --max-payload to zero
• Fix optional parameter parser in service mode
• Handle "0" in domain names (SNI)
• Fix --set-ttl when used with --min-ttl

Known bugs:

• --set-ttl after --auto-ttl does not work (does not disable auto-ttl) despite Fake requests, TTL: fixed in the status line (since v0.2.0)
• Not really a bug, but anyway: --max-payload 1200 would skip HTTP request block circumvention if the payload is large (if there's a lot of cookies for example).
