Add contest event to multiple calendars

[sahanmndl]

Currently on clicking the calendar button beside a contest name, it redirects to the google calendar add event page. But now it should have the option to add the event to 3 calendars (Google, Apple and Outlook).

• On clicking calendar button, open a small dropdown menu with the 3 options along with their logos
• Clicking on any option, should redirect to the add event page of that particular calendar, with title as the contest name, and start and end time same as that of the contest. Make sure that the start and end time are correct on all 3 calendars.
• The library currently being used should be able to add the event to Outlook as well as Apple calendar. If not, any other library can be used to replace this.
