Touchscreen support

Idk why I was worried that this would be difficult. Less than 20 lines of code later, Hadronize now automatically detects whether you’re using a fine pointer (e.g. a mouse) or a coarse pointer (e.g. a touchscreen), and changes its behavior accordingly.

So now you can select chambers on touchscreen just by tapping on them. You don’t have to drag the superposed quark, you just tap.

I recorded a video showcasing this in action using Firefox’s mobile device simulator (aka RDM). As you can see, when I disable touch simulation, the chambers respond to hovering and I have to drag the quark around. But when I enable touch, the chambers don’t react at all until I click one, and then the superposed quark gets added to that chamber like normal.

I’ve also tested this on an actual phone and it works perfectly, but it’s more difficult to record on there which is why I used Firefox’s simulator for the video.
