v0.1.9

New features

• Tonos-cli prints network name to which it is connected
• Tonos-cli prints path to config file
• Network url can be defined explicitly in any subcmd:
  tonos-cli --url <network_addr> <subcmd> ...
• Path to config file can be defined by environment variable or by command line option. The last one has a higher priority.
  tonos-cli --config <path_to_file> <subcmd> ...

Bug fixes

• Fixed key block query in getconfig subcmd
• Fixed bug when there is no key block
