fifteen, better sizing of the game to suit small screens
fifteen, improved graphism, now have a puzzle image

Now on each piece we have a puzzled image.
The number are proposed once on 2 levels.
traffic: add image mode and car images

Use car images in "IMAGE" mode which is now the default mode for
traffic. The rectangle/color based original version can be activated
by setting mode to "COLOR". This mode could become a per-activity
setting once we support them.

The added car*.svg files all come from openclipart.

Also change the truck svgs slightly by adding a tiny empty border to
avoid drawing them on the grid-lines.
traffic: add a minimum size for the grid

Fixes also the grid being smaller than the bounding box on small
resolutions.

Also let the red pass through the exit.
traffic: add reload button
lightsoff: fix layout for levels > 69
core, in the menu now the section highlight does follow the selection
money, fixed layout issue

The store area could wrap uncontrolled on 2 lines
