Redis Minify Cache Method Error

There is an issue with the Redis Cache Method for Minify.

Fatal error: $w3_cache is not defied on line 664
File: /w3-total-cache/Minify_MinifiedFileRequestHandler.php

I went into the file and the logic seems to be copy-pasted from Memcached and that’s because it does not work for redis.

Lines from 658 to 662 contain this:

if ( class_exists( 'Memcached' ) ) {
	$w3_cache = new Cache_Memcached( $config );
 } else if ( class_exists( 'Memcache' ) ) {
	$w3_cache = new Cache_Memcache( $config );
 }

While it should be like this to work:

if ( class_exists( 'Redis' ) ) {
	$w3_cache = new Cache_Redis( $config );
} 

Can you guys update this on the next version?
