Decompress deflated string while staying compatible with the majority of servers.

Certain servers will return deflated data with headers which PHP's gziniflate()
function cannot handle out of the box. The following function lifted from
http://au2.php.net/manual/en/function.gzinflate.php#77336 will attempt to deflate
the various return forms used.

@link http://au2.php.net/manual/en/function.gzinflate.php#77336

@param string $gzData String to decompress.
@return string|bool False on failure.
