Convert Boolean value into integer

Browse Source 
According to documentation, SQLite doesn't have a separate Boolean
storage class. Instead, values are stored as integers 0(false) and
1(true). In QSqlQuery::bindValue(), if a boolean value is bound
to a placeholder, it is converted to text true and false. This fix
converts boolean value to integer 0 and 1.
