Added cron.yaml file that will run every hour and update events.json file on remote datastore
main.py:
 imported urljoin to join location of server and name of file
 created storage_path and fullfilename variables; they are separate because storage_path might change
 created class UpdateHandler, which is used by the cronjob to update events.json
  it tries to get the file and write it to the datastore location using urlretrieve
  if it does not work, it logs an error
  changed and added comments
  created function that tries to get file from the storage location,
  if it does not work gets it from events.hackerdojo.com
  fixed parantheses on elif statement
