Make web controller more mobile friendly

[McSwindler]

I attempted to use the remote from my mobile phone, it worked for the most part, but I ran into some issues. I don't know how many people will actually be doing this, it might be a good option for some games and to play with people who may not have a controller setup on their PC.

1. While dragging the analog sticks, the web page scrolls around as well. Should disable the scroll function when the analog stick is focused.
2. Not all of the buttons fit on the same window, forcing to scroll up and down to use the L+R buttons. I know it can be tricky to fit it all on a small screen, and I don't anticipate people actually using their phone...so this is a minor thing.

Thanks for trying out the project! I did do somethings to make the page not scroll when the stick is selected but I can see how if you miss the stick, then you will accidently scroll. So you're really saying that while dragging the page does scroll? I'm using a Pixel 3. What phone are you trying it with? Sorry the about the buttons not fitting, again, I only really bothered to try on my phone cause like you said, I don't think many people will use this. Let me know what phone you have or the resolution and I can try to make it better for you.
