Fix links to code.google.com

The code.google.com links were funneling into a "issues migration" repo. Instead replace the download and wire protocol links with ones hosted at the SeleniumHQ website and the GitHub wiki respectively.

 This client aims to be as thin as possible, abusing the dynamic nature of PHP to allow almost all API calls to be a direct transformation of what is defined in the WebDriver protocol itself.
 
-Most clients require you to first read the protocol to see what's possible, then study the client itself to see how to call it.  This hopes to eliminate the latter step, and invites you to rely almost exclusively on http://code.google.com/p/selenium/wiki/JsonWireProtocol

 Each command is just the name of a function call, and each additional path is just another chained function call.  The function parameter is then either an array() if the command takes JSON parameters, or an individual primitive if it takes a URL parameter.
 
 The function's return value is exactly what is returned from the server as part of the protocol definition.  If an error is returned, the function will throw the appropriate WebDriverException instance.
