Subject: [PATCH] =?UTF-8?q?Version=201.7.1=20=E2=80=94=20auto=20default=5F?=
 =?UTF-8?q?page=20detection?=
MIME-Version: 1.0

- config.json now has default_page: auto for fresh installs
- CodePressCMS::detectDefaultPage() scans content/ for first available file
- getHomepageTitle() also respects auto mode
- Admin config form preserves auto as selectable option
- Save handler falls back to auto instead of index
