Compiling against current versions of spdlog

[gr3m1in]

Hi, I've faced the following errors while compiling bitz-server against spdlog versions 1.2.1-1.3.1.

main.cpp:39:24: error: ‘stdout_color_st’ is not a member of ‘spdlog’
  auto logger = spdlog::stdout_color_st( "bitz-server" );
main.cpp:78:20: error: ‘rotating_logger_mt’ is not a member of ‘spdlog’
   logger = spdlog::rotating_logger_mt( "bitz-server", config.log_file, ( 1048576 * 1024 ), 7 );

It appears that spdlog/sinks includes are missing, so the following patch helped

Latest spdlog version against which it now compiles is 1.3.1 Compiled using gcc 8.2.0-r6 If you need any additional information, feel free to ask :)

Kind regards, gr3m1in
