A form generator following conventions in WordPress short codes
- for each match:
- make it return the original markup
- make it return before/after change
- make a submit() method to send it somewhere
- make an "onComplete" feedback - green/red checkmark/x
- short-code-prompts.js is working; takes a single input or textarea
- short-code-forms.js is not yet -- need to decide how it converts each type of input (textarea, input, select, etc) into Markdown or HTML
