Add ScreenShot as a Standard Action

[accessor-io]

I request that screenshots are added as a preloaded action.
On Ubuntu and the keyboard I have, does not register the PrtSc key when requested to capture a key, using the 'key' action.
Can't find another solution to automate Screen Shots.

Flameshot in Ubuntu is one option by command line.

That's a good idea, and should not be very complicated to implement, too. Thanks.

Actually this is a duplicate of #205

No but you can contact me via the Discord server (and send a direct message there), or using e-mail (see the about box in Actiona).
