In-game keyboard for mobile devices

Add an in-game button this can enable or disable in video settings when in-game keyboard is disabled it will use external keyboard (your system keyboard or active keyboard) and when enabled will use a keyboard that is for minecraft only. This keyboard same as other keyboard but the symbols in it are those symbols valid in game, and has a shift and tab use for autocomplete the command, just same as how it work when minecraft is being controlled with keyboard and mouse.
