request: string translation support

[max-mapper]

We have a fork going over at https://github.com/maxogden/browserify-adventure-jp that is translating the problems to Japanese, but there are some things we can't override without forking:

• embedded english strings in source code
• no option to pass in custom usage.txt

For reference, here's a screenshot of how browserify-adventure-jp works now:
