[Mageia-artwork] Feature:InstallerLeftSideRedesign (need adopters/comments)

see https://wiki.mageia.org/en/Feature:InstallerLeftSideRedesign

in short, it means the left side of the installer could be partly 
clickable/partly dynamic changed depending on various options chosen or via 
which method/media you're installing.

ie: it looks differently if you're using live or DVD or network install and 
some consistency in the steps. if you're in a certain step, that step should 
be active and not the next/previous step.
