Choose if to display errors or not

If the status code returned by the geocoder API is anything other than "OK" an alert with the respective status code is shown to the user.

This doesn't really make sense for the common user as he isn't told for what exactly the error is displayed.

Example:
When using the macro in the meetings app, the error "Error: ZERO_RESULTS" isn't saying much about where it's coming from.

The display of errors should be optional through a parameter of the macro.

Improvement:
Fire events for each status code so that the developer using the macro in his app can handle errors in a way that is best suited for his needs.
