Android Port Using SDL

[TheBrokenRail]

Personally, I don't like reinventing the wheel for every platform. As such, I'm not the biggest fan of how the existing WIP Andorid port does so, especially when SDL has perfectly good Android support. I especially don't like how that port depends on VS (and therefore Windows) to build.

So here's my Android port using the existing SDL backend. It supports both multi-touch and showing the on-screen keyboard when appropriate.

The currently WIP port will not require Windows to build when it's merged in. I will personally port it to a gradle based project. It's only to get us up and running.

I still think it's better to avoid reinventing the wheel. Especially since SDL makes so many hard things (multitouch, on-screen keyboard, etc) so easy.

[iProgramMC]

Sure. I can pull your changes too as an alternative. I mean they build on your existing work anyway. I'd refuse if it was purely Android that's supported by SDL.

Think there's already a low resolution graphic of the Minecraft grass block in Brent's Apple stuff. I should think of an icon to replace it.

Edit: Not really, it's in game/assets/icon.png

[iProgramMC]

Please remove the Minecraft: Pocket Edition icon. We don't want to risk it. It's fine if it's iconless for now - the native Android port has no icon.

Also, it seems that immersive mode is turned off when the virtual keyboard is shown.

Also, the virtual keyboard has text prediction enabled for some reason, which is broken.

Also, please .gitignore the .idea repository.

Build was fixed for me, thanks!

I've made the changes!
