Fixes

• Fix memory problems with popups and inheritance

Additions

• New wifi_change event, triggered on wifi connect or disconnect

Changes

• All events are forced to run when invoking sketchybar --update, i.e. after
  the initial configuration. This makes initialization of items driven by
  events easier. E.g. an item displaying the front app name would have been
  empty till the first application switch event occurred, now the
  front_app_switched event is forced to be emitted by sketchybar --update,
  such that the item will be populated at startup without any additional logic.
• More detailed default config with simple event driven volume and wifi items
