[Automotive] Qt Virtual Keyboard

Hi Matt. We ran into this same problem at DocBox, there does not appear to
be a public API for custom keyboard layouts / styles. When we contacted
commercial support about wanting this feature, we were told the development
team "didn't see the value in it". This was over a year ago, and I haven't
checked in since. It's probably time to do that, I'll send a feature
request later today.

In the meantime, we made changes to Qt 5.7 Virtual Keyboard's source to
enable custom styling / layouts. The changes required to do so are very
small (a mere 4 lines!), but would need additional thought and work to
warrant submitting to the Qt project. Our custom virtual keyboard layouts /
styles (*.qml) are included as resources in a common library used by our
apps. We modify VirtualKeyboardStyles::styleImportPath() to search for
styles at a known qrc:// URL. To load custom layouts, we point
FolderListModel's "folder" property in Keyboard.qml to also point to a
known qrc:// URL. I hope this helps!
