Fixed four queries to correct the episode flags

templates/queries-correspondent-mysql.tpl.html,
templates/queries-correspondent-sqlite.tpl.html,
templates/queries-index-mysql.tpl.html,
templates/queries-index-sqlite.tpl.html: All SQL queries used a CASE
    expression to return either 'Explicit' or 'Clean' depending on the
    0/1 setting of the 'explicit' column. However, the TT² templates
    using these queries were written to expect the numeric form. All the
    'CASE' expressions have been replaced by the field name and now the
    correct flag is being displayed.
