Remove livereload cache buster param in extractId

[cgross]

When using grunt-contrib-watch for livereload and using less.js during development causes the reloading of less styles to happen incorrectly. Basically tiny-lr (used by grunt-contrib-watch) adds a query param to all the files it retrieves like "?livereload={{current time}}". Less.js then uses that url to try to extract the id of the given less file and sees each one as unique instead of the appropriate file.

This causes the livereload/less combination to add the styles from the changed less file but not remove the old ones. More discussion can be found here:

Thanks for tracking it down.
personally i compile serverside and use livereload to reload the css - much easier, but anyway will merge this for the next release. Unfortunately you just missed v2.0.0

Yea I realize I just missed it. No big deal. Whenever 2.0.1 goes out thats cool.

The thanks really go to @bpartridge.
