More powerful display and space selectors

[FelixKratz]

I had this in mind for some time now and this would be a good oportunity to refactor the bar_manager and bar code.
From the technical point of view this is all very simple, the hard part is to come up with a proper configuration syntax for this.
Obviously, the current configuration syntax should not be affected by this addition so it would need to be a command prefix.

Maybe something like:

sketchybar --bar <property>=<value> ... <property>=<value>

sets properties for the bar globally (as it is now), while

sketchybar --display <positive_integer list> --bar <property>=<value> ... <property>=<value>

would set the properties for the specified displays only.

Problem with this is that it looks as if it is a global display select and should therefore also work for items, e.g.

sketchybar --display <positive_integer list> --set name <property>=<value> ... <property>=<value>

should also only change the item properties on a specific display.

This would require significant modifications to the bar_item logic as well.

And when exposing a --display selector one could go even further and provide a --space selector as well, which should work for both the --bar and --set domains.

I will think about this some more but I like the idea so far. Any further ideas/considerations for this syntax addition?

This is a top-down, organized structure, which is a brilliant idea. I am eagerly looking forward to it.
