Subject: CodeIgniter ignores the set config value for Maximum Execution Time,
 overwriting it with its own value of 300 seconds. Whilst this is sensible in
 the vast majority of situations (browsers), when running a script from CLI,
 it is likely that execution times may need to be longer. Therefore, don't
 override the time limit if being run from the CLI - instead default back to
 PHP's own configuration.

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: URI Routing overhaul

 - Allow multiple levels of controller directories (supersedes PRs #390, #2439)
 - Add support for per-directory 'defaul_controller' and '404_override' (resolves issue #2611; supersedes PR #939)
 - Fixed a bug where default_controller was called instead of triggering 404 if the current route is inside a directory
 - Removed a few calls from CI_Router to CI_URI that made a necessity for otherwise internal CI_URI methods to be public:

    - Removed CI_URI::_fetch_uri_string() and moved its logic into CI_URI::__construct()
    - Removed CI_URI::_remove_url_suffix, CI_URI::_explode_segments() and moved their logic into CI_URI::_set_uri_string()
    - Removed CI_URI::_reindex_segments() altogether ( doesn't need further manipulation, while  is
      public anyway and can be properly (and more effectively) replaced on the spot)
