Fixing days to next free slot

Browse Source 
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.
