Added the `META name value` keyword to the SETHOOK command.
Allows for adding metadata to a webhook. For example:
SETHOOK myhook http://endpoint/ META m1 12 META m2 13 NEARBY ...
Would result in notification that contain the "meta" element, which is
represented like:
"meta":{"m1":"12","m2":"13"}
Thanks for the suggestion @amorskoy

Can now get back more details about an object:
NEARBY people FENCE ROAM people * 5000 SCAN :*
For more information see #96
Thanks @amorskoy for suggesting feature in #93Closes#96
It's now possible to mask the fence notifications based on the
command. For example, if we only want "set" and "del" commands.
NEARBY fleet FENCE COMMANDS set,del POINT 33 -115 10000
