Title: Use ng-class when possible

MInor PR, generalize the use of `ng-class` (improve code clarity)

Exhaustive list of components affected :
- Draw (current selected icon and current selected tool)
- Slider (divisions)
- Homescreen popover (when displayed)
- Body tag
- Import WMS (layer selected or hovered in the list)
- LayerManager (layer has a timestamp or not)
- Offline button (red when ther is offline data)

I've tested all and that works as expected
