Implemented support for changing resolutions and going fullscreen.

For the accompanying openfl-native pull-request.
One problem remains: Something calls SDL2Stage::SetScreenMode repeatedly, seemingly in response to mouse events. Don't know how that happens, added a small hack to ignore those calls.

Hey there, I've been messing around with your additions a bit but couldn't get it running. Is it possible to use lime with your extensions to control the fullscreen settings for an otherwise pure openfl-project?

Falls Du Dich dort auskennst würde ich etwas Hilfe in der Richtung sehr zu schätzen wissen. Ich versuche seit Monaten ein Problem in meinem Projekt zu lösen und bekomme es nicht hin. Würde mich freuen, wenn Du nen Augenblick Zeit hättest.

[RobDangerous]

Yes, that's possible. Will contact you on skype to figure out what's going wrong.

Hey Rob, thanks again for your patience.

You've done a great job of making sure that this is done in a way that doesn't impact the existing behavior. You've enabled something that is not otherwise possible right now.

I'm not sure if this will remain permanent, but if it does not, it will be because we've merged this functionality in a slightly different way.

I really appreciate your help, and hope that we won't let useful changes like this block in the future. Have a great day!

[RobDangerous]

Thanks, always glad to help.
