Allow to put multiples actions for buttons in Dialogs

Allow to put multiples actions for buttons in Dialogs (like run_command, show_dialog...) because If we want to execute an command and to open another dialog (without puting the cursor at the center) we can, or If we do'nt have permissions, we can execute multiple trigger commands, or we can re open the dialog and execute a command in the same time when we interacted with a button if the "pause" field is set to false and the "after_action" is set to "close"...
