Implement Software Keyboard GTK frontend (#1434)

Browse source 
* Implement SwKbd GUI

* Relocate UI handler to Emu Context from Config

Also create a common interface for UI handlers in the context and specialize for Gtk

Add basic input length validation in InputDialog

* Add Transfer Memory support to AppletCreator

Read Initial Text for SwKbd using Transfer Memory

* Improve InputDialog widget

Improve length validation
Has extra label to show validition info
Handle potential errors and log them

* Misc improvements

* Improve string validation
* Improve error handling
* Remove tuple in struct
* Address formatting nits

* Add proper Cancel functionality

Also handle GUI errors in UI handler

* Address jD's comments

* Fix _uiHandler init

* Address AcK's comments
