rewrite of keyboardq.qml, reduce stackview to 2, use a combobox for
keyboard models list
colors set to configurable
.xml files used for keyboard layouts, about a dozen added now
builds, runs, actions record as intended, GS filled correctly
added missing components listed as ResponsiveBase, ListItemDelegate & ListViewTemplate
parts of which were on nitrux
keyboard.qml no longer uses buttons within ListView, can't work as buttons and have them visible
see https://doc.qt.io/qt-5/qml-qtquick-listview.html#footerPositioning-prop
set ListView as actually visible within a normal calamares window size
- name default / example QML conventionally
- copy QRC from keyboard -- the QML needs to be included in the QRC --
since we don't want to have the QML in the keyboard module.
