Uptime via SNMP in monitor plugin

[Anarhyst266]

Hi all.
Sorry for my bad English, it isn`t native for me.
Some times ago I was looking for uptime plugin to see how long my switches are online. But in that forum i find only one plugin, and it doesn`t work for me. So i modified monitor plugin to show me this information.
Now I want to give it to your criticism. For his work, just replace the file [CactiPluginDir]/monitor/monitor.php


P.S. It works for me on Ubuntu 10.04 server, Cacti 0.8.8a, monitor plugin v1.3 and Plugin Architecture v3.1
