Change post formats to avoid rich-text YAML

[jrubenoff]

Not sure if we want to handle this, but if you have quote posts spanning multiple paragraphs, the post won't compile.

Every input, if only one in each form can be rich text:

Text

Title: Plain text. Want to avoid hard character limits here, as Fiona Apple-length titles are nice to have from a writing perspective. Body: Markdown.

Image

Description: Markdown.

Quote

Quote text: Markdown. Quote source name: Plain text. Quote source URL (future): Plain text. Notes: Plain text. If you want to write a quotation with multiple annotated paragraphs, use blockquotes in a text post. You might want to write a few sentences though, so this should still be a textarea.

Link

URL: Plain text. Title: Plain text. Notes: Markdown

Video

Code: Plain text Title / Creator (and all other future attribution fields): Plain text Notes: Markdown

@maxmechanic , any thoughts?
