Added Multiaddress extended call flow

This can be handy if there are more than 3 addresses involved in the dialog.
In the future, it could be implemented a way to show multiple unrelated dialogs in the
same flow.

* Fixed raw panel for extended call flow.
* Added color per dialog (capital C keybind)
Merged Call-Flow and Call-Flow-Ex into one screen

* Added some options like min space for raw message panel
* Added colored by Callid
* Added compatibility with multiple columns in call flow
* Added options to toggle raw message panel (t)
* Added options to toogle columns per callid (s)
Fixed a crash in Online mode with ngrep
