Allow markdown in Intros and Outros as an alternate to plain text

[ruqqq]

Should (at least partly) solve #17.

[ruqqq]

Still need to figure out how to render plain text of the markdowns (including the FreeMarkdown field?)

Thanks @ruqqq for the PR. Looks fine to me for now, but could you add/modify some examples and tests ? The goal is checking automatically with CI that Markdown is (and will be - with future changes) displayed as expected.

• tests are in hermes_test.go
• examples are in examples folder. Just go in it and launch go run *.go

To answer your question, plain text version of FreeMarkdown content is generated as follows:

1. Markdown -> HTML (with Blackfriday)
2. HTML -> Text (with htmlToText)

[ruqqq]

Will do so when I get some free time. Curious question: why aren't all the fields markdown enabled by default?

[matcornic]

@ruqqq Hmm, you're right. At first, when I created this issue, I thought I would make all fields Markdown enabled.
But we need to see if themes are robust enough with handling Markdown as well (e.g. Markdown in table)

[danielpoe]

All fields markdown support will be awesome.

Hey guys, is there a reason why this still hasn't been merged ? It's a pain to only have plaintext in intros and outros :(
