- Fixed flags for the readme mode, now they are disjoint. This fixed some
other related things.
- Renamed fancyindex_readme_options to fancyindex_readme_mode (shorter
and clearer, IMHO)
- Renamed fancyindex_mode to fancyindex_include_mode (clearer).
- Checks for bottom/top readme are now properly done.
- Fix: Initialization of readme_flags now is zero instead of NGX_CONF_UNSET.
- Improved iteration of builtin template.
