Remove query strings from static resources

<?php
/**
 * Remove Query Strings from Static Resources
 *
 * Strips version query strings (?ver=X.X) from CSS and JS URLs. Some CDNs
 * and proxy caches refuse to cache URLs with query strings, so removing them
 * can improve cache hit rates. The trade-off is that you lose automatic
 * cache busting on version updates — only use this if your CDN handles
 * purging or you use filename-based versioning.
 *
 * Usage: Add to functions.php.
