Trillian log server and signer config file does not allow comments

[font]

It would be great to allow comments in the config file for trillian_log_server and trillian_log_signer via the --config option. The library being used interprets everything as a token, even commented lines, which then fails to fully parse the actual config file options.

Maybe the way we should go with it is to use Cobra and Viper for better command line and configuration experience.
