implement custom protobuf debug string creation

[ebbit1q]

Short roundup of the initial problem

cockatrice generates a lot of debug output, which is great, but some things should not be logged, namely passwords and lengthy pictures/decklists

What will change with this Pull Request?

• creates function that uses protobuf's text format functionality to extend the normal logging with protective measures
• apply safe logger on all instances of getting a pb message debug string

example log:

I changed the logging behavior a bit so it no longer adds so many backslashes:
