Wild cards

Teachers can create questions like,

  How much is {apples} + {oranges}?

- where the {wildcards} become M and N × images of apples and oranges respectively. It is aimed at pre/primary-school students (approximately age 3-10).

Currently supported wildcards: apple, orange, pear, pineapple, walnut, cookie (each with or without an 's', eg. {cookies} and with an optional differentiator). For example,

  {apples_1} - {apples_2}

Tested with Moodle 1.9.7.
