Stage 1 — only .mkd-filtering is done.... NO customization of the mod_autoindex is done

Stage 2 — custom mod_autoindex

This probably entails switching from "everything is inside one script" to "everything is inside one directory", since we may need icons for that autoindex.

Stage 3 — ability to do 'grep -ris' searches from the web side

Stage 4 — add the ability to display page-history/diffs from a git repo; RecentChanges is provided by Git's commit log
