Title: Generate can fail if Pygments can't parse a code block

Currently, the entire generate task will fail if the user has asked Pygments to parse a language block it doesn't understand -- this can be due to a type, omitting the language, etc.

I think it's better to simply parse these blocks as plaintext in that case.
