Couple minor fixes within TeamLiquidNews

Makes sure we have at least 20 results for both featured/community in
JSON. Also fixes for when day is less than 10 (as it wouldn't select
month str properly in substr). Finally, introduced use of cURL into
simple_html_dom.php as get_file_contents is disabled on my web host. If
cURL fails, fallsback on get_file_contents, which hopefully doesn't fail
then.
