kill subscriber process when desktop is removed

[amtoine]

This is a duplicate of the stale #36 to apply the requested changed and merge the branch to master.

TODO:

• [x] make desktop_id=$(bspc query -D -d "$selected_desktop"); a standalone function inside utils/desktop.sh (see 36#discussion_r895042042)
• [x] "have 2 functions kill_layout and kill_process" (see 36#discussion_r895042221)

@phenax would you like me to apply the changes above from the original PR, without a review? or wrap them inside a review first?

no pressure if you do not have the time, that's just a friendly ping :relieved:

[phenax]

@amtoine, I think it's better if this pr contains those changes before the review if that's what you mean

@phenax the first point should be addressed in b38e145c and the second in 3186fc79 :yum: EDIT: and a bad typo below :eyes:

review can begin :muscle:
