Handle missing time zone data better

[mattjohnsonpint]

Currently, if you forget to load the time zone data, or you typo or make up a zone that doesn't exist, you get the local time.

moment().tz("Foo/Bar").format()

Instead, this should error with something like:

The zone "Foo/Bar" could not be found. Did you forget to load the time zone data file?

Or something like that.

This will improve the dev experience, as several questions get posted on StackOverflow where the only issue is that they didn't see or understand the instructions for loading the tz data.

Yeah, I think a console.error would be good here.

I'm considering removing the link to just the library on the download section and having the output from the data builder include both the library and the data. This way, you would always have some data loaded.

Check out the console here. http://jsfiddle.net/timrwood/nwY6m/

The nice thing about console.error is that you can get a stack trace of where the error is coming from.
