Patch to unify Android and iOS hint

patch

As discussed in 2012 the iOS onscreen keyboard hides when you hit RETURN (see https://discourse.libsdl.org/t/on-screen-keyboard-change/19216).
IMO this is a bad idea to not be able to influence this behavior and just recently this was fixed for Android by adding the hint SDL_HINT_ANDROID_RETURN_HIDES_IME in changeset 11768	0f2fb9ec6ad6.

I've included a little patch for this but you probably want to change the HINT name.

Perhaps it might be good to make this a shared hint for both Android and iOS but that would mean thinking about the correct default behavior.

Patch to unify Android and iOS hint

Added a patch to make this one hint for both Android and SDL "SDL_HINT_MOBILE_RETURN_HIDES_IME"
Comment 2 Sam Lantinga 2017-12-19 18:57:53 UTC 
I renamed the hint so this can apply on other platforms as well.
