Work in progress of form support in the slides

This will allow us to present interactive quizzes after topics to gauge
immediate student comprehension. We can quiz towards the end to gauge
retention as well.

This will also allow us to collect survey data directly, making us
Internet independent.

- Create HTML forms using custom markdown syntax
    - Can specify machine parsable keys & human readable labels
    - Supports radio/checkbox/select/text
    - Specify defaults for radio/checkbox/select
