Added new contests and self healing functionality

Added new contests from 31 oct to 21 dec 2014
Self healing -- If database/table is not found, a new database/table is
created instead of displaying error.
Added fast mode to reload.php -- loads contests and problem list for each
contest without loading each problem's page. Does NOT create
directories/files for each contest

Known bugs:
Latest contests - QUCO2014 and ICPC14PR have not been added. Even their
end times have been gone.
