[Observium] Submission of code

Hi Everyone,

I've recently added some minor functionality to assist with the monitoring of our networks. A summary of this would be:

* ShoreTel OS Logo * ShoreTel OS definition * Added SonicWall firewall CPU OID and related graphing * Added Sonicwall firewall active sessions discovery and graph definition for this

To achieve this, there are a couple of extra .inc.php files and some addition snippets added to existing files. I understand that you prefer code submissions through wget from a website and I can arrange this, but firstly would like to know if you are interested in adding my code (following a review of course) to the product. Would make my pulls from SVN much easier!!

Thanks,

John.
