Stable release

With the push to release PhpGt repositories to their stable versions, this release includes the single piece of functionality that was holding it back from being integrated within WebEngine: the ability to assign a prefix to the XPath query.

This is used within the PhpGt/Dom repository to allow typical child-based searches, but also parent-based searches for using DOM functionality such as $element->closest($selector).

The library has been in use within WebEngine for a number of weeks so is receiving its first stable release, and even though advanced functionality like :not selector is missing right now (and admittedly, doing advanced CSS selectors within your server-side code is probably a bad idea), we're looking forward to adding more completeness to the library for future releases.

Have fun and stay productive!
