GitLab

if the audio voices or effects are disabled,
tell the user that this activity will play audio anyway

works in both explore_farm_animals and explore_world_music

still need to prevent having several GCDialog called at same time, but that's a separate issue

now when closing a GCDialog with the cross or the esc key,
if there's a button2 (typically a "no" answer), it clicks that button
else if there's only a button1 (typically an "ok" button), it clicks that button,
else if there's no button it just closes as before

allow GCDialog to have keyboard focus, and always give it back to its parent
fix usage of checkForVoices to give the activity as parent
fix to avoid englishFallbackDialog at same time as Missing sound files dialog
fix to not try to destroy englishFallbackDialog as it can not be destroyed

new activity learn_digits

Activity is fully functional,
though I still need to add a layout variant state for vertical screen,
and make a few controls improvements

display the full activity titles as much as possible
use elide only if the text can really not fit with the minimumPointSize

enable image and audio tips by default

also clean/simplify a bit the ActivityConfig code
(similar to how it works in share activity for example)
