[PreRelease] TeamSpeak 3 Server 3.7.0 Beta

[Rikku]

today we released the first beta for upcoming server 3.7.0.

• This server version adds a new feature that the upcoming (not yet released) "TeamSpeak 5 client" needs.
  The TS 3 client & ServerQuery will not see anything new here but it could be that user interactions may have a bigger impact on CPU & RAM.
  
  So please hold an eye on your system and report back if something strange is going on or feels slower on your server.
  Even when it's something like "the channel creation / subscription takes longer".
  For us it would be helpful if you have something we can compare. Like the same action on stable version 3.6.1 was different.

• We improved the speed when ServerQuery requests the clients from database with command clientdblist
• The permissions for ancient audio codecs Speex and CELT got removed.
  The codecs can not be set on channel anymore. Channels where the codec was set before still can be used.
  In future release we will drop these codecs completely.
• Admins can now see in the server log who deleted the avatar from a user when client logging was active.
• The connected ServerQuery will not show the IP in the nickname any longer. Admins can see the IP in the server log or via clientinfo command (see changelog).
