VoIP dialogs: Improvements and new functions

Changes:
- RTP Player added to Telephony/RTP menu.
- When openning RTP Analysis or RTP Player from RTP menu, just selected
  stream is added. When Ctrl is hold during opening, reverse stream is
searched and added too.
- RTP Player: Added tool to select/deselect all inaudible streams
- RTP Player: Added Prepare Filter button
- RTP Player: Added Analyze button
- RTP Analysis: Added Prepare Filter button
- documentation updated

Code changes:
- RTP Player::rescanPacket() is not fired multiple times during rate change and during dialog creation
- Error shown in RTP player is cleared after every new decode of streams
- RTP Player handles case when Qt do not emit stop stream event
- "Select" menu code unified between dialogs>
- RTP Player: Audio routing menu unified
- buttons are connected to actions by signals()
- Analyze dialog is called by list of rtpstream_id, not rtpstream_info
