Subject: [PATCH] Ported from godot:  Fix Android input routing logic when
 using a hardware keyboard When a hardware keyboard is connected, all key
 events come through so we can route them directly to the engine. This is not
 the case for soft keyboards, for which the current logic was designed as it
 requires extra processing. - m4gr3d
