Add WoL sending capability

Builds a json payload to consume the ogServer API to send
WoL packets.

Adds 'send' as a command:

	ogcli send

Adds a wol object for to the 'send' command, so that sending a wol can
be specified as:

	ogcli send wol

* WoL packet type is specified with --type option.
* Specifying targets follows same parameters as 'set modes' with:
	--client-ip
	--room-id
	--center-id
