* Actually check if map save succeeded before displaying success message
It would be great to offer more clarity to the mapper about *why* the
save didn't succeed, but at least they won't be deceived into thinking
their work has been saved when it hasn't.
Portuguese localization text is via DuckDuckGo Translate, so I hope it's
reasonable.
* Actually check save success for saving grids
These messages need localization, too, but that seems out of scope for
my PR.
* Improve map save error message
Now it tells the mapper to go look at the server log.
Still translated via DuckDuckGo Translate.
* Normalize indentation and style
