Suggestion: show modal on all displays not just one

[PaulMorris]

Given an open laptop connected to an external display (or several?), I found that the modal appeared only on the laptop's screen and not the external display. I think it would be better if the modal appeared on all displays so you would always see it, no matter which screen you are looking at.

I have a small edit that does this, that's working for me locally, and I'd be glad to submit a pull request if there is interest.

(Also, many thanks for this wonderful project! I am really enjoying the ways it is improving my time spent staring at screens and pushing buttons.)

Personally, I don't use more than two displays at the moment, but I'm sure a few people probably would like this. Also, it seems we currently show the HUD only on the main screen (that's the default behavior of hs.alert.show), maybe we should also have an option to make it appear on the active screen (where the mouse cursor is). So, perhaps an enum, with values like main, active, all.
Thank you for the idea and for the kind words.

If feel this would be best tackled via #72 or as a config option as I had experimented with this prior to the refactor and found it was obtrusive when watching fullscreen videos on another screen while looking up a word definition in Alfred for instance. If you feel this would make a better default, then the advising system would at least allow me to make it work like the current behavior without having to replace the whole call chain.

Sample fix:

;; Make alerts show on all screens
(import-macros {: defadvice} :lib.advice.macros)
(defadvice alert-all
           [str style seconds]
           :override alert
           "Replace core.alert with one that alerts on all screens"
           (each [_ screen (pairs  (hs.screen.allScreens))]
             (hs.alert.show str
                            (or style 1)
                            screen
                            seconds)))
