Ability to process the linked channel by default in the TeamTalk account.

[artem59k]

Hello. I propose to implement a feature that will allow you to receive a default channel from the TeamTalk server in your account. This will allow you to change channel passwords without hindrance, without involving an administrator to edit the configuration file. And it will also avoid the moment when users change their password without warning, and as a result TTMediaBot cannot join the channel. Thanks.

@artem59k Your proposal looks interesting. I am not sure that it is even possible with current python TeamTalk wrapper but if it is, we will try to implement requested feature.
