'locale' config option is not optional

[bredmor]

The README says this option is optional, however failing to specify it causes a javascript error from vendor.js - locale is not defined.

I have the same issue.

I couldn't reproduce it unfortunately. Can you please share a minimal code that causes this error?

should be fixed within version 0.2.2
