IOS7: Toggle keyboard with on-screen control button

Browse Source 
Add a long press gesture to the touch mode control button, which
when triggered, shows the keyboard. The image of the UI button
changes to the keyboard image asset as long as the keyboard is
visible. If pressing the touch mode control button while the
keyboard is visible it will dismiss the keyboard.

The updates of the on-screen button image is done in the general
"showKeyboard" and "hideKeyboard" functions which makes sure that
the button image is updated also if showing/hiding of the keyboard
is triggered by the OSystem callback.
