* Set up bootstrap for phpunit
Fix issues with FileExistsException
* Attempt to fix phpunit
* Fix classloader and bootstrap to use full paths only (not depending on $config)
* Fix phpunit tests, config.php does not exist.
* Implement an autoloader
When cleaning up classes for psr2, things got a bit unwieldy, so I implemented a class autoloader.
I created a PSR-0 compliant LibreNMS directory and moved all classes there that made sense.
Implemented LibreNMS\ClassLoader which supports adding manual class mappings
This reduces the file includes needed and only loads classes when needed.
* Add teh autoloader to graph.php
* Add a small bit of docs
Fix incomplete class in includes/discovery/functions.inc.php
