Chrome. Log websoket activity to log file from devtools. -- 3

Chrome developer tools currently able to show websocket traffic for selected websocket connection for a tab. Need to add functionality to log all messages (both sent and received) to a text file. Work result should be provided as patch to chrome source code. Start logging may require user to open devtools, selecting WS connection at first. I.e. need to save everything that already present on browser devtools screen to a file. So just log already available data to a file.

- Log all Chrome devtools -> network -> websoket (in + out messages) to text file.
- Provide work result as patch to Chrome source code (C++ programming language)

File could be like:

S: sent message 1
R: received message 1
S: sent message 2
R: received message 2
and so on.

Thanks for feedback.
