GitLab

CI has broken because of some new
AppStream validation requirements
in the master image. So, base the
CI of 3.32 on 3.32 runtime image.

Yay git.

With agreement from Masuichi Ito, of course.

Also, update http links to https.

Do not expose actions over D-Bus, the API
has not been thought or designed for now.

The undo stack is really oversized,
but the previous formula was highly
misleading, as it was based on a 64
tiles board (not depending onto the
size of said board), and suggesting
the max number of possible flipping
tiles is reached in the corner (and
I now think that this is not true).
