Conflict with jsdom

[wesleyaboyer]

I don't know what exactly the issue is, but when I require sentence-tokenizer in my project, jsdom no longer works correctly.

Well that is a well documented example of how to not add an issue in a lib.. :(

This may be due to the usage of sugarjs, which modified the string prototype.
I got rid of it for version 1.0.0
