Feature: send complete config on barconfig_update 

Send all the options in the bar block on the barconfig_update event.

This will eventually allow for dynamically updating bar colors with the
`reload` command.

=== barconfig_update event
This event consists of a single serialized map reporting on options from the
barconfig of the specified bar_id that were updated in i3. The map always
consists of a property +id (string)+, which specifies to which bar instance the
sent config update belongs, a property +hidden_state (string)+, which indicates
the hidden_state of an i3bar instance, and a property +mode (string)+, which
corresponds to the current mode.
*Example:*
---------------------------
{
"id": "bar-0",
"hidden_state": "hide"
"mode": "hide"
}
---------------------------
barconfig of the specified bar_id that were updated in i3. This event is the
same as a +GET_BAR_CONFIG+ reply for the bar with the given id.
