Allow freeform lasering on mobile

Previously you could double-tap to ping. You can still do that and now if you double-tap and then drag you can freeform laser!

It’s a bit of a weird interface, and I think I have my work cut out for me making tutorial info for mobile, but I do think it’s quite nice :slight_smile:.

I believe this is the last of the capabilities I’ll be adding. I think a mobile player can now do everything a desktop player can do. Now I’ll get to figure out how to make tutorial info for all this.

Happy Shmepping ya’ll!
