- site-generator is generic, so no changes.
- removed mysql information from site.cfg.
- Updated template files to call sqlite queries directly.
- Renamed the query files - remove sqlite from file names.
- Deleted MySQL specific template files.
templates/content-index.tpl.html: the `TT²` algorithm can be simplified
because the new query returns less. We get the date of the show
before the free slot, and can increment it differently depending on
whether the previous show is on a Friday or not - catering for
weekends in other words!
templates/queries-index-mysql.tpl.html,
templates/queries-index-sqlite.tpl.html: using a 'find unused index
numbers' query available in many places on the Internet, but
modified to return the id number and date for the show *before* the
next free slot.
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.
templates/queries-index-mysql.tpl.html,
templates/queries-index-sqlite.tpl.html: Enhanced the query that finds
the next free slot (query_next_available_episode). Also made it
compute the days to the slot from the current day. The query returns
data for calling Date::Calc to compute the number of days, but this
calculation is no longer necessary. Next release will remove this.
templates/content-index.tpl.html: The number of days to the next free
slot is reported here. The original Date::Calc computation which did
this is no longer needed and has been removed since the query
(query_next_available_episode) does it.
