Add "various" cube (a cube type without scrambler)

[Domalar]

A new "Varous" puzzle type without scrambler (scramble is no shown). So everybody can use the sessions in this type of puzzle for puzzles that does not fit into others (eg. slide puzzles like 15-puzzle or 2x2x3, 3x3x4 aso.).

Sorry for the duplicate commit with the correction of the typo (same commit in 2 pull requests).
