sshproxy v1.5.0

Changes in v1.5.0:

Add an option to force the command executed by sshproxy.
Add an option to close the connection when original command does not match de force command.
Add an option to translate the command to something else.

Warning: there is a configuration change! A configuration is needed for SFTP to work as before. Please have a look at config/sshproxy.yaml and add the "translate_commands" block. You may need to change "internal-sftp" to something else if you're using something else than "internal-sftp". The value must be the same as the SFTP subsystem defined in your sshd_config.
