add RPiPlay app

Closes https://github.com/Botspot/pi-apps/pull/487

I decided against using debs, because like https://github.com/Botspot/pi-apps/pull/1953, rpiplay is a relatively fast compile and doesn't take up much space.

Also I added a run script (modified from @CleanMachine1 's here) which asks the user which audio output device (hdmi or analog) they would like to use each time they open the desktop entry.

@ryanfortner did you not see the comments in that issue? I don't think we care for RPIPlay anymore since it seems worse in all cases than UXPlay https://github.com/FDH2/UxPlay

I saw your comments. I still think rpiplay is worth adding because it aims to run well even on low spec models like Raspberry Pi Zero. Since the GPU on all Raspberry Pi models are not very powerful at all, it's important to at least give a reliable option.

In my testing, rpiplay works flawlessly on all my pies (I hook them up to a tv frequently for streaming and it's quite useful)

I'm not saying that UxPlay shouldn't be added though. Both seem like good applications to me 😀

you are assuming that uxplay also does not work flawless. it started as a fork of rpiplay so I doubt it runs worse

its all gstreamer, just chose the correct decoder and video sync and they will be the same

I will leave it up to @Botspot if he wants both applications or just one.

Would @ryanfortner be willing to test out uxplay to see if the performance is really worse or not?
