Subject: [PATCH] =?UTF-8?q?Next=20free=20slot=20algorithm=20now=20in=20TT?=
 =?UTF-8?q?=C2=B2=20form?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

templates/content-index.tpl.html: Now contains TT² code and an in-built
    query to determine the next free slot. No need for an external
    query. Old code that used to use this has been deleted.

templates/queries-index-mysql.tpl.html,
templates/queries-index-sqlite.tpl.html: Old queries called
    'query_next_available_episode' removed since no longer needed.
