feat: adds keyboard shortcuts

[pedrolamas]

Adds support for keyboard shortcuts!

Keyboard Shortcuts dialog (shown with ?)

Button tooltips (shown only if Keyboard Shortcuts are enabled)

Settings entry

Both the pause and cancel shortcuts conflict with some firefox shortcuts (new private window and element picker respectively), and while Ctrl+Shift+C seems to work fine when printing (only opens the element picker when the printer is idle), Ctrl+Shift+P always opens a new private window for me

I have a feeling I am opening a can of worms here... I'm going to check the keyboard shortcuts that Gmail uses and try to use those (should be safer, I guess...)

I've set Pause to Shift+p and Cancel to Shift+c, seems to work fine in Chrome/Edge and Firefox...

I now got myself thinking... arrows to control the toolhead? 😁

Like Shift+arrow key and that would move the toolhead in the indicated direction by 10mm?

With just Shift+P and Shift+P I now can't type any upper case commands containing a C or P in the console while a print is running ;) I assume the event handler is just missing the eventTargetIsContentEditable call tho 😁

I guess that could work - maybe it could even use the configured move distances using the number keys, but that'd be a lot of combinations to remember haha

Oops... fixed now! 🙂
