Subject: Added support for Wincache when running CI on Windows boxes

Wincache is directly analogous to APC, except with less problems on a Windows environment. Performance wise they are almost identical (for user mode caching at least).

Need to have the Wincache PHP module downloaded from http://www.iis.net/download/wincacheforphp.

Subject: Bumped CodeIgniter's PHP requirement to 5.2.4. Yes I know PHP 5.4
 just came out, and yes I know PHP 5.3 has lovely features, but there are
 plenty of corporate systems running on CodeIgniter and PHP 5.3 still is not
 widely supported enough. CodeIgniter is great for distributed applications,
 and this is the highest we can reasonably go without breaking support. PHP
 5.3 will most likely happen in another year or so. Fingers crossed on that
 one anyway...

Subject: Cache Driver - Backup Never Loaded The condition that checks to see
 if the backup driver input is valid was prefixing the input with "cache_".
 Since the valid driver values don't have this prefix, the condition was
 always returning FALSE and the backup drivers were never being loaded. I've
 removed the prefix in the condition and added a debug log message for when
 the backup driver is used.
