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: Docblock improvements to the Config library and remove
 CI_Config::_assign_to_config()

Existance of _assign_to_config() is pointless as this method
consists just of a foreach calling CI_Config::set_item() and
is only called by CodeIgniter.php - moved that foreach() in
there instead.

Subject: config->site_url() optimizations

- direct access to config array, instead of item() calls
- the string cast is just in case 'url_suffix' would be set to false or null; the function produces the same results without this cast, but it leads to a robuster code, as false and null are sanitized and skip the suffix insertion code
- altered conditional structure: if no suffix, skip the appending of an empty string to $uri

Subject: Yet another method for determining "base_url"

This one is great because we don't have to deal with the special cases:
* in Windows, dirname('/foo/index.php') gives "/foo", but dirname('/index.php') gives "\" instead of "/"
* dirname() doesn't include the trailing slash, with the expection of "/" (root)

Subject: [ci skip] Change some log messages' level

'Class Loaded' type of messages flood log files when
log_threshold is set to 2 (debug). They're now logged
as 'info' level.

This is manually applying PR #1528, which was created
to do the same thing, but became outdated.
