manual: db.in.ogr add column type detection for CSV (#4883)

* manual: db.in.ogr add column type detection for CSV

Improve CSV import example with GDAL related column type autodetection (suggested by @cmbarton).

Fixes #4674 (see also related issue #4593).

* minor HTML fixes

* imageryintro.html: fix typo; add missing img alt; add missing </li>
