Fixes #150 Adding default text for event entries not specified

[ritankarsaha]

Fixes #150

This PR does the following:-

1. Modifies the index.html page in the events_news folder of the templates folder.
2. Whenever there is an empty field, while creating an event through the admin portal, it displays N/A instead of leaving it blank.
3. Used basic if block to conditionally check whether the fields are filled or not and thereby display the proper message accordingly,

PROOF OF WORK

This Screen Recording shows the entire process and also displays when the fields are not filled, it's displaying N/A and it also shows that when the fields are filled all the content are displayed. Therefore it does not hamper the general process

Additional Screenshots to support it-

Thank You.

@SamakshAgarwal1112 @NightFury742 I have completed the issue #150 and linked a PR for the same #154

[SamakshAgarwal1112]

@ritankarsaha Events are listed at home page also. At home page, events are listed with "Location" entry. Add a default text there as well. Also, when we click View on an event, A detailed page is opened with all of event details. Add default texts for location and event entries there as well.

@SamakshAgarwal1112 @NightFury742 I have made the necessary changes as desired and pushed a new commit into the PR.
The new commits -

1. Modified the event.html file of the events_news folder both for mobile screens and PC screens to display the empty fields as N/A, whenever a card is clicked on the view component to display the enlarged acrd.
2. Modifies the index.html of the Alumni connect folder so that the cards displayed under the Events section display N/A when the fields are not filled.

PROOF OF WORK

This video demonstrates all the 3 places where the cards are and where N/A should be displayed instead of the empty fields.

This displays the photo of the card in the home page of the website.

This displays the photo of the card when the view button is clicked and it gets enlarged displaying the whole card.

This shows the original cards in the events section sbowing that it didnot mess up the previous commits.
