Add a new API call to "systeminfo" class, which returns

information about all processes on the system.

The below example was greatly truncated ;)

REST Request:
-------------------------------
PUT /sysadm/systeminfo
{
   "action" : "procinfo"
}

REST Response:
-------------------------------
{
    "args": {
        "procinfo": {
                  "228": {
        "command": "adjkerntz",
        "cpu": "3",
        "nice": "0",
        "pri": "52",
        "res": "1968K",

        "username": "root",
        "wcpu": "0.00%"
          }
        }
    }
}

WebSocket Request:
-------------------------------
{
   "id" : "fooid",
   "namespace" : "sysadm",
   "name" : "systeminfo",
   "args" : {
      "action" : "procinfo"
   }
}
