Added as an export option "Experimental Virtual Keyboard". There is no zoom, so text/line edit must be in the top part of the screen, or it will get hidden by the virtual keyboard. UTF8/Latin-1 only (I think regular UTF-8 should work out of the box in 4.0 but I can't test it). It uses an hidden textarea or input, based on the multiline variable, and only gets activated if the device has a touchscreen. This could cause problems on devices with both touchscreen and a real keyboard (although input should still work in general with some minor focus issues). I'm thinking of a system to detect the first physical keystroke and disable it in case, but it might do more harm then good, so it must be well thought.
