Disable syntax guessing for PygmentsCodeFences by default

Browse source 
This disables highlighting for fenced code blocks without explicitly specified language. It also introduces a new `PygmentsCodeFencesGuessSyntax` config option (defaulting to false).

To enable syntax guessing again, add the following to your config file: `PygmentsCodeFencesGuessSyntax = true`

This is a breaking change.
