SaltGUI should always use full

Is your feature request related to a problem? Please describe. Some commands return only very simple information, like true/false. This is indistinguishable from the return of false on a timeout.

Describe the solution you'd like The API should use full_return as much as possible. The response from that clearly indicates success/failure as well as a separate result.

Update: while the data is better separated from the meta-data, it does not indicate success/failure. instead, it provided a result-code separate from the results. but the indication for success/failure is still missing.

Update: this is only relevant for free-format commands, not for the internal commands. When internal commands fail we don't show much extra information anyway.

Update: this must be arranged as a setting saltgui_use_full_return: True (default: False) as this is a breaking change. not only will the gui show different output, also the job history as maintained by the SaltStack system will change a little bit. And that may be an unpleasant surprise for some.
