Overview

Registers Premonition hooks in Jekyll.

Two hooks are added. One general hook for pages and another special hook for dealing with excerpts within posts.

This ladder is really a hack as we scan all Markdown files and insert the excerpt ourselves in the document data. Unfortunately Jekyll prepares the excerpt way to early in the process, preventing us from hooking into it in a prober way. We only support excerpts if the excerpt_separator is explicitly set: jekyllrb.com/docs/posts/#post-excerpts
