Apply g:ale_echo_msg_format to :ALEDetail messages

When Displaying the error with either `:ALEDetail` it would be fanstantic to have a sumarized linter and rule.

So instead of displaying the following from eslint:
```
no allowed console
```

It would help SO much if we prefix with the rule and engine complaning such as:
```
eslint (no-console): no allowed console
```

So that we can instanlty modify our .json or .rc file to add the rule, or simple add the ignore rule comment. And since all engines differ on how to ignore/disable rules, it's really important to understand if the error is comming from either `tslint`, `eslint`, `tsserver`, etc....

I hope I was able to explain my self.
