Voice commands issues

See the attached image (commands.png):
+ Rename the label: "Speech Command List" to "Voice command list"
+ Rename the column "Command Key" to "Voice command"

See the attached image (edit.png):
+ If you edit a command the form says "Add command" it should say "Edit command". Also please rename the label "Command Key (Required)" to "Voice command (Required)".
+ The submit button should say "Update" instead of "Add"
+ Rename the label "Key Word" to "Key phrase" (this also applies when you are adding a new command).
+ If you edit a command and you change its "Voice command" value then it doesn't update the command it creates a new one.

If you create or edit a command but you don't specify a key phrase then the app doesn't recognize the voice command.

After you have finished please update the app's wiki text and pictures.
