semantic views creates string class attribute while it must be an array

Semantic Views creates an attribute: "class" => "clear-block".
Tao then adds a class: $...attributes['class'][] = "bla"; < fatal error

The problem: Semantic Views creates a string, where everybody (Toa in this case) expects an array.

The fix: simply replace all the strings with arrays =)

Patch included. (Patch created with GIT, so inc object id etc.)
