2.x

Here's the latest version of the 2.x branch. It contains a the following changes:

- Completed the conversion to CodeIgniter
- Converted PHP code to follow a [community coding standard](http://www.php-fig.org/)
- Removed duplicate and deprecated code. No new functionality except for bug fixes.
- Ported the new installer. Changed defaults to use "vshell2." Can be run side-by-side with a V-Shell v1 instance on the same machine.

The last piece missing is the XML/JSON data exports. Need Mike's input on the state of the backend data exports in V-Shell v1 and how to proceed implementing them in V-Shell v2. Should be pretty straight forward.

This is a drop-in replacement for V-Shell v1 functionality and a good platform for evolving V2 in the future.

For what it's worth, the standardizing of the PHP formatting made the diffs rather large. I'd suggest cloning the repo and looking at the code directly.

Tested with Nagios Core on CentOS 6.5 (yum) and Debian 7.3 (apt).

Let me know if you have any questions,

Cheers!
