Update to latest CodeIgniter version

[frederickding]

So I've only been playing with OpenVBX for a few hours, but I realized that there were a few shortcomings that could be fixed by tapping into a higher version of CodeIgniter. (Notably, PDO database driver, better session security, etc.)

I've managed to make the full manual upgrade to CodeIgniter 2.1.4, but it involved non-trivial changes to this application's files and folder structure (basically following these procedures):

• moving MY_Controller, MY_Model, and User_Controller to a new OpenVBX/core/ directory
• updating config files with the bundled versions in CodeIgniter, for mimes.php, user_agents.php, etc
• correcting subclasses of Controller to CI_Controller, Model to CI_Model
• adding an encryption key
• adding a constant to index.php

Despite the complexity, I now have a working installation at https://tel.penn-nec.org/ .

Are there any plans currently to update the version of the library used?
