views: add direct cmd execution view

Reorganize "Run" section of Commands view as follows:

Commands
  └── Run
    ├── Script: run script from folder
    ├── Cmd: direct command execution
    └── Display output: results of last execution

Adapt API REST call to the new interface. Remove strange legacy
;|\n\r terminator. Remove "echo" field and add "inline" field.
