Touch focus events

[curiousdannii]

Currently in Quixe, you must tap the input box precisely in order to bring up the soft keyboard. It would probably be better to allow the user to tap anywhere in a window to focus the input (compare with Parchment which does this.)

If the input is already focused, tapping the window elsewhere will hide the keyboard and then show it again. This is far from ideal! Tapping the window should either not affect the soft keyboard, or it should hide the keyboard. It may not be possible to do the first, so perhaps tapping the window could toggle the keyboard on and off.
