RegExp Adaptive mode with Help (no penalties)

This plugin is one of the 2 question behaviours to be used exclusively with the regexp question type. Those behaviours enable you to take advantage of the *Help* feature, which allows the student to “buy” a letter. This behaviour does not cost the student any penalty when “buying” a letter.
Selecting a mode other than  None  will display a button to enable the student to get the next letter or word (including the very first letter or word).
In  Adaptive No penalty  mode the button displayed will say “Get next letter” or “Get next word”.
