…rmation from the api when importing listings

the idx-api.php client_properties() function adds ?disclaimers=true to all requests made through it, so including ?disclaimers=true in the initial request results in our API not including the disclaimer when it returns results

…true

since this data originates from our API and is never modified by the user, it should be fine to output it directly to the page

… when there are more than 50 featured listings on an account

the next value returned by the api does not include disclaimers=true even if it's included in the initial request, so it needs to be added back if a subsequent query needs to be made to fetch all the listings.
