swaybar: complete barconfig_update event handling

This adds complete support for the barconfig_update ipc event. This also
changes the bar command and subcommand handlers to correctly emit the
event. This makes it so all bar subcommands other than id and
swaybar_command are dynamically changeable at runtime. sway-bar.5 has
been updated accordingly
