Add Android Touchpad Only Control Option

[FearlessSpiff]

Hi

Thanks for this great app, I only had one problem with it on Android:

I added an option to use the touchpad button without anything else on the android client. As the DS4 controller is only supported in Andorid 10 it helps as a workaround for all those trying to play with the DS4 with games using also the touchpad (Jedi, Fallen Order for me atm :-)). Maybe also other controllers. Tested it with my Pixel 3 and Tab S6. So with this PR you are able to play without on screen controls but just show the touchpad button in the bottom right.

Maybe you can incorporate it. It surely isn't the cleanest solution. And as I am new to Andorid Apps, I am open to suggestions. If they are not too time consuming as I have kids, a.s.o... ;-)

Thanks for considering

Doesn't look too bad, I think it makes sense to have this extra control layout with controls that might not be available on the physical controller. I will check it in detail tomorrow.
Only one request for now though: Please only use tabs in Kotlin code, TouchpadOnlyFragment.kt currently has spaces.

Btw don't worry about the failing travis job, I have yet to fix this for prs.

Ugh... I fixed it in my initial branch based on your repo. Then I forked and forgot it. Will change it with a
ammend/force push. I think Android Studio settings default to spaces, that's why...

Great. My local builds worked so far...
