Make GitHub-Markdown a default bundle - #23
Merged
Conversation
Move the "Markdown (GitHub)" catalogue entry from AvailableBundles.plist (opt-in) to DefaultBundles.plist (auto-install) so a fresh install gets GFM highlighting and preview out of the box. The warm-on-install hook installs its gems (redcarpet, rouge) at install time. The entry is otherwise unchanged.

A fresh install now gets GFM syntax highlighting and preview out of the box. The warm-on-install hook (#22) installs the bundle's gems (redcarpet, rouge) at install time, so the first preview is ready without a cold lazy install.
Note
This means a default bootstrap now performs a network + native-extension compile step (redcarpet is a C extension) for this bundle. That is the intended consequence of shipping it by default.
