0.12.0

• Improved: better sorting of results (eg. mariadb 10 now comes after mariadb 5)

• Improved: dbconsole command: sql:execute learned to replace tokens in the value of --output-file, eg: --output-file '../shared/results_{instancename}.yml'

• New: dbstack learned a new command: monitor. It will open an interactive, textual admin console, which gives useful information about the running containers (eg. cpu and memory usage)
