Subject: [PATCH] Detect Kulturhauptdorf events by tag name instead of tag ID
 21
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The event detail template data set has_tag_21 to drive the
Kulturhauptdorf logo, but tag 21 is "Feste & Märkte", so the logo
showed on every market/festival event. Add is_kulturhauptdorf, which
checks for a tag named "Kulturhauptdorf" (case-insensitive), and keep
has_tag_21 as deprecated for backwards compatibility.
