FS#10338: Add "use morse input " entry to settings menu

* Remember last used text input mode (keyboard or morse input) in settings.
* Add setting "Use Morse Code Input" under Settings -> General Settings -> System.

Now it is possible for some of targets without button combo for changing input mode to use morse input by changing the setting. it's not possible for them to change input mode during in the keyboard screen of course.
There are still targets without morse input mode.
