/**
* This replaces the default MooTools more Depender.request function to use
* HTTP "get" rather than "post".
*
* When sending requests for files via the depender, I was finding that Safari
* wasn't getting and re-evaluating them the second time I visited the page.
* This was because an etag was sent with each script.
*
* Safari responds to etags properly and adds "If-None-Match" and
* "If-Modified-Since" headers to another request for the same file. This makes
* Apache respond with a 412 status (Precondition Failed) as it should do for
* "post" requests (according to RFC 2616).
*
* Unfortunately Safari doesn't then deal with the 412 as it does with a 304
* (Not Modified). It doesn't grab what it has in the cache and put it in the
* response, it gives you nothing.
*
* For "get" requests, Apache has to respond with a 304, or 200 or whatever, but
* not 412. So we change the request method so we don't have to deal with 412.
