Title: Add support for ScaleQuestions

This adds support for scale questions, including:
* Randomize the direction of the scale, with support for an anchor
* Multiple rows (attributes) with the same scale
* Randomization goes the same direction for multiple attributes
* Shuffle the ordering of multiple rows
