Add support for string arrays about wmi

[gbrayut]

See https://github.com/bosun-monitor/scollector/blob/win_network/metadata/metadata_windows.go#L78 for an instance where this is blocking. When trying to use the IPAddress property as either a []string or a string I get the following error:

2014/11/10 18:49:33 error: metadata_windows.go:37: wmi: cannot load field "IPAddress" into a "[]string": unsupported type
2014/11/10 18:50:02 error: metadata_windows.go:37: wmi: cannot load field "IPAddress" into a "string": unsupported type

Also for some reason the MACAddress does not work as a string. Error message:

2014/11/10 19:10:45 error: metadata_windows.go:37: wmi: cannot load field "MACAddress" into a "string": unsupported type
