Rename override to overwrite.

This breaks the API, but I think it just makes way more sense to call it overwrite since that's the name of the option in Bugsnag, and actually means what it does--override sounds like changing functionality.

Alternatively, could change the README to match override. But since no one's really using this yet, might as well nip it in the bud?

Thanks @flushentitypacket, I'm still testing these plugins quite a bit, so I appreciate you finding this small gem 😛

@jacobmarshall FWIW there's another repo here doing a similar thing as well: https://github.com/bakunyo/bugsnag-sourcemap-webpack-plugin

I had to fork it to get it working for my use case, but it's pretty well done and lightweight. Could consolidate efforts!

Nice, didn't know one already existed - I'm getting in touch now.
