- Modified module to check for .xml endings as well and thus change the
  request's Accept header to application/xml
- Removed a semicolon at the end of the if clause on line 7 as per javascript
  conventions (JSLint)
- Changed the README.md to account for the inclusion of the xml check
- Updated the version to 0.0.3 in package.json
- Forgot to put the ` character around .xml in the README.md
Merge pull request #1 from jwyuen/master
