Add initial voice-capabilities binding support
Add support for subscribing to and using the guimetadata events from the vshl-capabilities binding. A GuiMetadata class is used to wrap things as it is likely that users of the other voice capabilities would not overlap if e.g. navigation event support is later added. At the moment, only the BodyTemplate1, BodyTemplate2, and WeatherTemplate guimetadata types are handled, and there is room for significant improvement in the Qt model exposed, which is somewhat crude with respect to image URL handling. As well, the weather template handling does not expose the full forecast, a full implementation of that would require adding an actual model that maps to a list view rather than a simple QObject. Bug-AGL: SPEC-3110 Signed-off-by: Scott Murray <scott.murray@konsulko.com> Change-Id: I33fc2440ebdc2a4a2de79ff0a49acbc422c47da2
