detect new monitors / refresh detected monitors

[sebsel]

Describe the feature

Maybe I am missing something, but I can't seem to find a way to get LeftWM to discover new monitors after it has been launched.

Current behavior: I am working on my laptop. Then I move to my desk, plug in a monitor. My computer does not automatically detect the new monitor, so I run xrandr --auto to make it available. LeftWM will duplicate the workspace on both monitors.

What I want: let LeftWM create a new workspace for the new monitor.

My current solution: kill LeftWM and reboot it (which means I loose all my open applications).

The same goes for when I unplug: there will still be a workspace for the unplugged monitor, which means I sometimes loose the focus (when I focus something on the monitor that isn't there). It would be nice to run a command and have LeftWM remove the unused workspace.

How important is this feature to you?

My workflow is impaired without it

How important do you think is this feature for the average LeftWM user?

I already prepared some work, see #1058.

It's basically missing a hook to reload the theme.
