* feature: allow validate.php to be run from any working directory
* remove redundant realpath() call
* re-add realpath() to remove symbolic links
* realpath() isn't needed...
* chdir() in all php scripts in ./ and ./scripts/
* update-sql.php clearly is not used, as it was broken.
* Change some scripts to executable
Remove extra chdir() call in snmp-scan.php
* Missed console-ui.php
Kind of fixed console-ui.php help output
* Re-add newline
* 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
